Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702538, here are decompositions:

  • 41 + 8702497 = 8702538
  • 79 + 8702459 = 8702538
  • 107 + 8702431 = 8702538
  • 127 + 8702411 = 8702538
  • 151 + 8702387 = 8702538
  • 167 + 8702371 = 8702538
  • 179 + 8702359 = 8702538
  • 197 + 8702341 = 8702538

Showing the first eight; more decompositions exist.
