Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604906, here are decompositions:

43 + 31604863 = 31604906
103 + 31604803 = 31604906
139 + 31604767 = 31604906
163 + 31604743 = 31604906
349 + 31604557 = 31604906
373 + 31604533 = 31604906
397 + 31604509 = 31604906
409 + 31604497 = 31604906

Showing the first eight; more decompositions exist.
