Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603976, here are decompositions:

43 + 31603933 = 31603976
97 + 31603879 = 31603976
367 + 31603609 = 31603976
409 + 31603567 = 31603976
457 + 31603519 = 31603976
487 + 31603489 = 31603976
727 + 31603249 = 31603976
829 + 31603147 = 31603976

Showing the first eight; more decompositions exist.
