Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617136, here are decompositions:

3 + 31617133 = 31617136
59 + 31617077 = 31617136
107 + 31617029 = 31617136
113 + 31617023 = 31617136
137 + 31616999 = 31617136
149 + 31616987 = 31617136
233 + 31616903 = 31617136
389 + 31616747 = 31617136

Showing the first eight; more decompositions exist.
