Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472006, here are decompositions:

3 + 31472003 = 31472006
67 + 31471939 = 31472006
73 + 31471933 = 31472006
157 + 31471849 = 31472006
367 + 31471639 = 31472006
373 + 31471633 = 31472006
457 + 31471549 = 31472006
619 + 31471387 = 31472006

Showing the first eight; more decompositions exist.
