Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520354, here are decompositions:

37 + 31520317 = 31520354
181 + 31520173 = 31520354
337 + 31520017 = 31520354
367 + 31519987 = 31520354
421 + 31519933 = 31520354
571 + 31519783 = 31520354
601 + 31519753 = 31520354
643 + 31519711 = 31520354

Showing the first eight; more decompositions exist.
