Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515414, here are decompositions:

13 + 31515401 = 31515414
31 + 31515383 = 31515414
37 + 31515377 = 31515414
61 + 31515353 = 31515414
97 + 31515317 = 31515414
103 + 31515311 = 31515414
107 + 31515307 = 31515414
113 + 31515301 = 31515414

Showing the first eight; more decompositions exist.
