Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617070, here are decompositions:

41 + 31617029 = 31617070
47 + 31617023 = 31617070
59 + 31617011 = 31617070
71 + 31616999 = 31617070
83 + 31616987 = 31617070
137 + 31616933 = 31617070
167 + 31616903 = 31617070
179 + 31616891 = 31617070

Showing the first eight; more decompositions exist.
