Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618714, here are decompositions:

3 + 31618711 = 31618714
11 + 31618703 = 31618714
167 + 31618547 = 31618714
251 + 31618463 = 31618714
311 + 31618403 = 31618714
353 + 31618361 = 31618714
503 + 31618211 = 31618714
521 + 31618193 = 31618714

Showing the first eight; more decompositions exist.
