Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567974, here are decompositions:

13 + 31567961 = 31567974
43 + 31567931 = 31567974
233 + 31567741 = 31567974
257 + 31567717 = 31567974
281 + 31567693 = 31567974
293 + 31567681 = 31567974
331 + 31567643 = 31567974
337 + 31567637 = 31567974

Showing the first eight; more decompositions exist.
