Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472696, here are decompositions:

109 + 31472587 = 31472696
337 + 31472359 = 31472696
457 + 31472239 = 31472696
487 + 31472209 = 31472696
547 + 31472149 = 31472696
643 + 31472053 = 31472696
757 + 31471939 = 31472696
1033 + 31471663 = 31472696

Showing the first eight; more decompositions exist.
