Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626242, here are decompositions:

13 + 31626229 = 31626242
163 + 31626079 = 31626242
223 + 31626019 = 31626242
331 + 31625911 = 31626242
421 + 31625821 = 31626242
463 + 31625779 = 31626242
643 + 31625599 = 31626242
733 + 31625509 = 31626242

Showing the first eight; more decompositions exist.
