Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476158, here are decompositions:

61 + 31476097 = 31476158
127 + 31476031 = 31476158
229 + 31475929 = 31476158
331 + 31475827 = 31476158
379 + 31475779 = 31476158
409 + 31475749 = 31476158
547 + 31475611 = 31476158
577 + 31475581 = 31476158

Showing the first eight; more decompositions exist.
