Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471952, here are decompositions:

13 + 31471939 = 31471952
19 + 31471933 = 31471952
103 + 31471849 = 31471952
241 + 31471711 = 31471952
271 + 31471681 = 31471952
313 + 31471639 = 31471952
331 + 31471621 = 31471952
373 + 31471579 = 31471952

Showing the first eight; more decompositions exist.
