Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604150, here are decompositions:

13 + 31604137 = 31604150
163 + 31603987 = 31604150
271 + 31603879 = 31604150
307 + 31603843 = 31604150
349 + 31603801 = 31604150
433 + 31603717 = 31604150
439 + 31603711 = 31604150
541 + 31603609 = 31604150

Showing the first eight; more decompositions exist.
