Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471976, here are decompositions:

37 + 31471939 = 31471976
43 + 31471933 = 31471976
127 + 31471849 = 31471976
313 + 31471663 = 31471976
337 + 31471639 = 31471976
397 + 31471579 = 31471976
619 + 31471357 = 31471976
769 + 31471207 = 31471976

Showing the first eight; more decompositions exist.
