Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626350, here are decompositions:

13 + 31626337 = 31626350
103 + 31626247 = 31626350
157 + 31626193 = 31626350
241 + 31626109 = 31626350
271 + 31626079 = 31626350
277 + 31626073 = 31626350
331 + 31626019 = 31626350
397 + 31625953 = 31626350

Showing the first eight; more decompositions exist.
