Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609364, here are decompositions:

97 + 31609267 = 31609364
151 + 31609213 = 31609364
271 + 31609093 = 31609364
277 + 31609087 = 31609364
331 + 31609033 = 31609364
541 + 31608823 = 31609364
547 + 31608817 = 31609364
571 + 31608793 = 31609364

Showing the first eight; more decompositions exist.
