Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618462, here are decompositions:

53 + 31618409 = 31618462
59 + 31618403 = 31618462
101 + 31618361 = 31618462
173 + 31618289 = 31618462
251 + 31618211 = 31618462
263 + 31618199 = 31618462
269 + 31618193 = 31618462
401 + 31618061 = 31618462

Showing the first eight; more decompositions exist.
