Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465466, here are decompositions:

  • 7 + 31465459 = 31465466
  • 103 + 31465363 = 31465466
  • 157 + 31465309 = 31465466
  • 223 + 31465243 = 31465466
  • 283 + 31465183 = 31465466
  • 313 + 31465153 = 31465466
  • 337 + 31465129 = 31465466
  • 367 + 31465099 = 31465466

Showing the first eight; more decompositions exist.
