Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596548, here are decompositions:

7 + 31596541 = 31596548
37 + 31596511 = 31596548
157 + 31596391 = 31596548
241 + 31596307 = 31596548
397 + 31596151 = 31596548
421 + 31596127 = 31596548
499 + 31596049 = 31596548
541 + 31596007 = 31596548

Showing the first eight; more decompositions exist.
