Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472054, here are decompositions:

13 + 31472041 = 31472054
43 + 31472011 = 31472054
223 + 31471831 = 31472054
373 + 31471681 = 31472054
421 + 31471633 = 31472054
433 + 31471621 = 31472054
463 + 31471591 = 31472054
643 + 31471411 = 31472054

Showing the first eight; more decompositions exist.
