Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476188, here are decompositions:

19 + 31476169 = 31476188
31 + 31476157 = 31476188
157 + 31476031 = 31476188
277 + 31475911 = 31476188
409 + 31475779 = 31476188
439 + 31475749 = 31476188
577 + 31475611 = 31476188
607 + 31475581 = 31476188

Showing the first eight; more decompositions exist.
