Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740290, here are decompositions:

  • 17 + 8740273 = 8740290
  • 71 + 8740219 = 8740290
  • 103 + 8740187 = 8740290
  • 107 + 8740183 = 8740290
  • 127 + 8740163 = 8740290
  • 151 + 8740139 = 8740290
  • 173 + 8740117 = 8740290
  • 179 + 8740111 = 8740290

Showing the first eight; more decompositions exist.
