Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518414, here are decompositions:

61 + 31518353 = 31518414
71 + 31518343 = 31518414
101 + 31518313 = 31518414
113 + 31518301 = 31518414
127 + 31518287 = 31518414
233 + 31518181 = 31518414
241 + 31518173 = 31518414
251 + 31518163 = 31518414

Showing the first eight; more decompositions exist.
