Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626494, here are decompositions:

13 + 31626481 = 31626494
73 + 31626421 = 31626494
127 + 31626367 = 31626494
157 + 31626337 = 31626494
421 + 31626073 = 31626494
541 + 31625953 = 31626494
577 + 31625917 = 31626494
673 + 31625821 = 31626494

Showing the first eight; more decompositions exist.
