Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471898, here are decompositions:

67 + 31471831 = 31471898
277 + 31471621 = 31471898
307 + 31471591 = 31471898
349 + 31471549 = 31471898
487 + 31471411 = 31471898
541 + 31471357 = 31471898
691 + 31471207 = 31471898
727 + 31471171 = 31471898

Showing the first eight; more decompositions exist.
