Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497214, here are decompositions:

  • 131 + 31497083 = 31497214
  • 251 + 31496963 = 31497214
  • 257 + 31496957 = 31497214
  • 293 + 31496921 = 31497214
  • 431 + 31496783 = 31497214
  • 521 + 31496693 = 31497214
  • 641 + 31496573 = 31497214
  • 647 + 31496567 = 31497214

Showing the first eight; more decompositions exist.
