Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581048, here are decompositions:

  • 7 + 581041 = 581048
  • 19 + 581029 = 581048
  • 67 + 580981 = 581048
  • 79 + 580969 = 581048
  • 109 + 580939 = 581048
  • 157 + 580891 = 581048
  • 211 + 580837 = 581048
  • 241 + 580807 = 581048

Showing the first eight; more decompositions exist.
