Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626390, here are decompositions:

  • 41 + 8626349 = 8626390
  • 89 + 8626301 = 8626390
  • 107 + 8626283 = 8626390
  • 251 + 8626139 = 8626390
  • 281 + 8626109 = 8626390
  • 347 + 8626043 = 8626390
  • 389 + 8626001 = 8626390
  • 431 + 8625959 = 8626390

Showing the first eight; more decompositions exist.
