Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472096, here are decompositions:

43 + 31472053 = 31472096
67 + 31472029 = 31472096
157 + 31471939 = 31472096
163 + 31471933 = 31472096
433 + 31471663 = 31472096
457 + 31471639 = 31472096
463 + 31471633 = 31472096
547 + 31471549 = 31472096

Showing the first eight; more decompositions exist.
