Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626170, here are decompositions:

3 + 31626167 = 31626170
61 + 31626109 = 31626170
97 + 31626073 = 31626170
151 + 31626019 = 31626170
349 + 31625821 = 31626170
397 + 31625773 = 31626170
409 + 31625761 = 31626170
439 + 31625731 = 31626170

Showing the first eight; more decompositions exist.
