Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497202, here are decompositions:

  • 131 + 31497071 = 31497202
  • 239 + 31496963 = 31497202
  • 281 + 31496921 = 31497202
  • 383 + 31496819 = 31497202
  • 419 + 31496783 = 31497202
  • 461 + 31496741 = 31497202
  • 509 + 31496693 = 31497202
  • 683 + 31496519 = 31497202

Showing the first eight; more decompositions exist.
