Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1058, here are decompositions:

  • 7 + 1051 = 1058
  • 19 + 1039 = 1058
  • 37 + 1021 = 1058
  • 61 + 997 = 1058
  • 67 + 991 = 1058
  • 139 + 919 = 1058
  • 151 + 907 = 1058
  • 181 + 877 = 1058

Showing the first eight; more decompositions exist.
