Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520044, here are decompositions:

107 + 31519937 = 31520044
167 + 31519877 = 31520044
251 + 31519793 = 31520044
383 + 31519661 = 31520044
443 + 31519601 = 31520044
461 + 31519583 = 31520044
557 + 31519487 = 31520044
587 + 31519457 = 31520044

Showing the first eight; more decompositions exist.
