Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626870, here are decompositions:

  • 23 + 8626847 = 8626870
  • 29 + 8626841 = 8626870
  • 47 + 8626823 = 8626870
  • 59 + 8626811 = 8626870
  • 107 + 8626763 = 8626870
  • 137 + 8626733 = 8626870
  • 173 + 8626697 = 8626870
  • 179 + 8626691 = 8626870

Showing the first eight; more decompositions exist.
