Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745390, here are decompositions:

  • 23 + 8745367 = 8745390
  • 37 + 8745353 = 8745390
  • 47 + 8745343 = 8745390
  • 61 + 8745329 = 8745390
  • 79 + 8745311 = 8745390
  • 83 + 8745307 = 8745390
  • 149 + 8745241 = 8745390
  • 151 + 8745239 = 8745390

Showing the first eight; more decompositions exist.
