Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626464, here are decompositions:

3 + 31626461 = 31626464
43 + 31626421 = 31626464
97 + 31626367 = 31626464
127 + 31626337 = 31626464
271 + 31626193 = 31626464
547 + 31625917 = 31626464
643 + 31625821 = 31626464
691 + 31625773 = 31626464

Showing the first eight; more decompositions exist.
