Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472084, here are decompositions:

31 + 31472053 = 31472084
43 + 31472041 = 31472084
73 + 31472011 = 31472084
151 + 31471933 = 31472084
373 + 31471711 = 31472084
421 + 31471663 = 31472084
463 + 31471621 = 31472084
673 + 31471411 = 31472084

Showing the first eight; more decompositions exist.
