Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626476, here are decompositions:

109 + 31626367 = 31626476
139 + 31626337 = 31626476
229 + 31626247 = 31626476
283 + 31626193 = 31626476
367 + 31626109 = 31626476
397 + 31626079 = 31626476
457 + 31626019 = 31626476
523 + 31625953 = 31626476

Showing the first eight; more decompositions exist.
