Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588734, here are decompositions:

41 + 31588693 = 31588734
61 + 31588673 = 31588734
103 + 31588631 = 31588734
127 + 31588607 = 31588734
131 + 31588603 = 31588734
173 + 31588561 = 31588734
211 + 31588523 = 31588734
241 + 31588493 = 31588734

Showing the first eight; more decompositions exist.
