Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725042, here are decompositions:

  • 3 + 8725039 = 8725042
  • 5 + 8725037 = 8725042
  • 59 + 8724983 = 8725042
  • 113 + 8724929 = 8725042
  • 239 + 8724803 = 8725042
  • 401 + 8724641 = 8725042
  • 563 + 8724479 = 8725042
  • 719 + 8724323 = 8725042

Showing the first eight; more decompositions exist.
