Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542486, here are decompositions:

7 + 31542479 = 31542486
29 + 31542457 = 31542486
47 + 31542439 = 31542486
67 + 31542419 = 31542486
89 + 31542397 = 31542486
109 + 31542377 = 31542486
113 + 31542373 = 31542486
127 + 31542359 = 31542486

Showing the first eight; more decompositions exist.
