Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582716, here are decompositions:

37 + 31582679 = 31582716
43 + 31582673 = 31582716
83 + 31582633 = 31582716
89 + 31582627 = 31582716
103 + 31582613 = 31582716
107 + 31582609 = 31582716
127 + 31582589 = 31582716
157 + 31582559 = 31582716

Showing the first eight; more decompositions exist.
