Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613794, here are decompositions:

11 + 31613783 = 31613794
167 + 31613627 = 31613794
281 + 31613513 = 31613794
353 + 31613441 = 31613794
383 + 31613411 = 31613794
461 + 31613333 = 31613794
503 + 31613291 = 31613794
677 + 31613117 = 31613794

Showing the first eight; more decompositions exist.
