Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472626, here are decompositions:

89 + 31472537 = 31472626
137 + 31472489 = 31472626
443 + 31472183 = 31472626
467 + 31472159 = 31472626
503 + 31472123 = 31472626
557 + 31472069 = 31472626
659 + 31471967 = 31472626
719 + 31471907 = 31472626

Showing the first eight; more decompositions exist.
