Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626332, here are decompositions:

103 + 31626229 = 31626332
139 + 31626193 = 31626332
223 + 31626109 = 31626332
313 + 31626019 = 31626332
379 + 31625953 = 31626332
421 + 31625911 = 31626332
571 + 31625761 = 31626332
601 + 31625731 = 31626332

Showing the first eight; more decompositions exist.
