Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604252, here are decompositions:

61 + 31604191 = 31604252
373 + 31603879 = 31604252
409 + 31603843 = 31604252
541 + 31603711 = 31604252
571 + 31603681 = 31604252
643 + 31603609 = 31604252
733 + 31603519 = 31604252
859 + 31603393 = 31604252

Showing the first eight; more decompositions exist.
