Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472882, here are decompositions:

3 + 31472879 = 31472882
31 + 31472851 = 31472882
43 + 31472839 = 31472882
109 + 31472773 = 31472882
271 + 31472611 = 31472882
433 + 31472449 = 31472882
523 + 31472359 = 31472882
643 + 31472239 = 31472882

Showing the first eight; more decompositions exist.
