Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626254, here are decompositions:

7 + 31626247 = 31626254
61 + 31626193 = 31626254
181 + 31626073 = 31626254
337 + 31625917 = 31626254
433 + 31625821 = 31626254
487 + 31625767 = 31626254
523 + 31625731 = 31626254
601 + 31625653 = 31626254

Showing the first eight; more decompositions exist.
