Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619348, here are decompositions:

37 + 31619311 = 31619348
67 + 31619281 = 31619348
139 + 31619209 = 31619348
157 + 31619191 = 31619348
307 + 31619041 = 31619348
331 + 31619017 = 31619348
349 + 31618999 = 31619348
367 + 31618981 = 31619348

Showing the first eight; more decompositions exist.
