Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613374, here are decompositions:

17 + 31613357 = 31613374
41 + 31613333 = 31613374
83 + 31613291 = 31613374
131 + 31613243 = 31613374
257 + 31613117 = 31613374
347 + 31613027 = 31613374
383 + 31612991 = 31613374
461 + 31612913 = 31613374

Showing the first eight; more decompositions exist.
