Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542624, here are decompositions:

11 + 31542613 = 31542624
37 + 31542587 = 31542624
101 + 31542523 = 31542624
137 + 31542487 = 31542624
167 + 31542457 = 31542624
227 + 31542397 = 31542624
233 + 31542391 = 31542624
251 + 31542373 = 31542624

Showing the first eight; more decompositions exist.
