Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496074, here are decompositions:

17 + 31496057 = 31496074
47 + 31496027 = 31496074
227 + 31495847 = 31496074
317 + 31495757 = 31496074
383 + 31495691 = 31496074
557 + 31495517 = 31496074
563 + 31495511 = 31496074
593 + 31495481 = 31496074

Showing the first eight; more decompositions exist.
