Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617126, here are decompositions:

53 + 31617073 = 31617126
97 + 31617029 = 31617126
103 + 31617023 = 31617126
113 + 31617013 = 31617126
127 + 31616999 = 31617126
139 + 31616987 = 31617126
193 + 31616933 = 31617126
197 + 31616929 = 31617126

Showing the first eight; more decompositions exist.
