Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538804, here are decompositions:

61 + 31538743 = 31538804
151 + 31538653 = 31538804
163 + 31538641 = 31538804
181 + 31538623 = 31538804
223 + 31538581 = 31538804
277 + 31538527 = 31538804
313 + 31538491 = 31538804
331 + 31538473 = 31538804

Showing the first eight; more decompositions exist.
