Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474292, here are decompositions:

  • 43 + 31474249 = 31474292
  • 79 + 31474213 = 31474292
  • 151 + 31474141 = 31474292
  • 163 + 31474129 = 31474292
  • 181 + 31474111 = 31474292
  • 709 + 31473583 = 31474292
  • 769 + 31473523 = 31474292
  • 1009 + 31473283 = 31474292

Showing the first eight; more decompositions exist.
