Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472108, here are decompositions:

67 + 31472041 = 31472108
79 + 31472029 = 31472108
97 + 31472011 = 31472108
277 + 31471831 = 31472108
397 + 31471711 = 31472108
487 + 31471621 = 31472108
751 + 31471357 = 31472108
937 + 31471171 = 31472108

Showing the first eight; more decompositions exist.
