Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626962, here are decompositions:

19 + 31626943 = 31626962
79 + 31626883 = 31626962
271 + 31626691 = 31626962
373 + 31626589 = 31626962
463 + 31626499 = 31626962
541 + 31626421 = 31626962
733 + 31626229 = 31626962
769 + 31626193 = 31626962

Showing the first eight; more decompositions exist.
