Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539044, here are decompositions:

37 + 31539007 = 31539044
157 + 31538887 = 31539044
331 + 31538713 = 31539044
373 + 31538671 = 31539044
421 + 31538623 = 31539044
463 + 31538581 = 31539044
487 + 31538557 = 31539044
541 + 31538503 = 31539044

Showing the first eight; more decompositions exist.
