Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540758, here are decompositions:

31 + 31540727 = 31540758
59 + 31540699 = 31540758
79 + 31540679 = 31540758
89 + 31540669 = 31540758
101 + 31540657 = 31540758
107 + 31540651 = 31540758
127 + 31540631 = 31540758
229 + 31540529 = 31540758

Showing the first eight; more decompositions exist.
