Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626370, here are decompositions:

3 + 31626367 = 31626370
11 + 31626359 = 31626370
47 + 31626323 = 31626370
137 + 31626233 = 31626370
173 + 31626197 = 31626370
179 + 31626191 = 31626370
239 + 31626131 = 31626370
317 + 31626053 = 31626370

Showing the first eight; more decompositions exist.
