Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528624, here are decompositions:

3 + 31528621 = 31528624
11 + 31528613 = 31528624
173 + 31528451 = 31528624
191 + 31528433 = 31528624
251 + 31528373 = 31528624
311 + 31528313 = 31528624
383 + 31528241 = 31528624
467 + 31528157 = 31528624

Showing the first eight; more decompositions exist.
