Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542504, here are decompositions:

17 + 31542487 = 31542504
47 + 31542457 = 31542504
67 + 31542437 = 31542504
107 + 31542397 = 31542504
113 + 31542391 = 31542504
127 + 31542377 = 31542504
131 + 31542373 = 31542504
163 + 31542341 = 31542504

Showing the first eight; more decompositions exist.
