Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542526, here are decompositions:

3 + 31542523 = 31542526
17 + 31542509 = 31542526
47 + 31542479 = 31542526
89 + 31542437 = 31542526
107 + 31542419 = 31542526
149 + 31542377 = 31542526
167 + 31542359 = 31542526
293 + 31542233 = 31542526

Showing the first eight; more decompositions exist.
