Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618702, here are decompositions:

239 + 31618463 = 31618702
293 + 31618409 = 31618702
383 + 31618319 = 31618702
491 + 31618211 = 31618702
503 + 31618199 = 31618702
509 + 31618193 = 31618702
569 + 31618133 = 31618702
641 + 31618061 = 31618702

Showing the first eight; more decompositions exist.
