Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472984, here are decompositions:

97 + 31472887 = 31472984
157 + 31472827 = 31472984
211 + 31472773 = 31472984
373 + 31472611 = 31472984
397 + 31472587 = 31472984
547 + 31472437 = 31472984
691 + 31472293 = 31472984
853 + 31472131 = 31472984

Showing the first eight; more decompositions exist.
