Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626146, here are decompositions:

37 + 31626109 = 31626146
67 + 31626079 = 31626146
73 + 31626073 = 31626146
127 + 31626019 = 31626146
193 + 31625953 = 31626146
229 + 31625917 = 31626146
367 + 31625779 = 31626146
373 + 31625773 = 31626146

Showing the first eight; more decompositions exist.
