Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538924, here are decompositions:

37 + 31538887 = 31538924
97 + 31538827 = 31538924
181 + 31538743 = 31538924
211 + 31538713 = 31538924
271 + 31538653 = 31538924
283 + 31538641 = 31538924
367 + 31538557 = 31538924
397 + 31538527 = 31538924

Showing the first eight; more decompositions exist.
