Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626098, here are decompositions:

19 + 31626079 = 31626098
79 + 31626019 = 31626098
181 + 31625917 = 31626098
277 + 31625821 = 31626098
331 + 31625767 = 31626098
337 + 31625761 = 31626098
367 + 31625731 = 31626098
499 + 31625599 = 31626098

Showing the first eight; more decompositions exist.
