Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476318, here are decompositions:

67 + 31476251 = 31476318
79 + 31476239 = 31476318
131 + 31476187 = 31476318
149 + 31476169 = 31476318
199 + 31476119 = 31476318
389 + 31475929 = 31476318
409 + 31475909 = 31476318
491 + 31475827 = 31476318

Showing the first eight; more decompositions exist.
