Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542536, here are decompositions:

13 + 31542523 = 31542536
79 + 31542457 = 31542536
97 + 31542439 = 31542536
139 + 31542397 = 31542536
163 + 31542373 = 31542536
307 + 31542229 = 31542536
373 + 31542163 = 31542536
433 + 31542103 = 31542536

Showing the first eight; more decompositions exist.
