Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147380292, here are decompositions:

  • 19 + 2147380273 = 2147380292
  • 73 + 2147380219 = 2147380292
  • 103 + 2147380189 = 2147380292
  • 151 + 2147380141 = 2147380292
  • 163 + 2147380129 = 2147380292
  • 193 + 2147380099 = 2147380292
  • 241 + 2147380051 = 2147380292
  • 313 + 2147379979 = 2147380292

Showing the first eight; more decompositions exist.
