Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472036, here are decompositions:

7 + 31472029 = 31472036
97 + 31471939 = 31472036
103 + 31471933 = 31472036
373 + 31471663 = 31472036
397 + 31471639 = 31472036
457 + 31471579 = 31472036
487 + 31471549 = 31472036
823 + 31471213 = 31472036

Showing the first eight; more decompositions exist.
