Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618504, here are decompositions:

41 + 31618463 = 31618504
101 + 31618403 = 31618504
293 + 31618211 = 31618504
311 + 31618193 = 31618504
317 + 31618187 = 31618504
383 + 31618121 = 31618504
443 + 31618061 = 31618504
461 + 31618043 = 31618504

Showing the first eight; more decompositions exist.
