Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626266, here are decompositions:

19 + 31626247 = 31626266
37 + 31626229 = 31626266
73 + 31626193 = 31626266
157 + 31626109 = 31626266
193 + 31626073 = 31626266
313 + 31625953 = 31626266
349 + 31625917 = 31626266
487 + 31625779 = 31626266

Showing the first eight; more decompositions exist.
