Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473908, here are decompositions:

7 + 31473901 = 31473908
61 + 31473847 = 31473908
97 + 31473811 = 31473908
127 + 31473781 = 31473908
379 + 31473529 = 31473908
421 + 31473487 = 31473908
577 + 31473331 = 31473908
691 + 31473217 = 31473908

Showing the first eight; more decompositions exist.
