Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542546, here are decompositions:

23 + 31542523 = 31542546
37 + 31542509 = 31542546
59 + 31542487 = 31542546
67 + 31542479 = 31542546
89 + 31542457 = 31542546
107 + 31542439 = 31542546
109 + 31542437 = 31542546
127 + 31542419 = 31542546

Showing the first eight; more decompositions exist.
