Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476312, here are decompositions:

29 + 31476283 = 31476312
61 + 31476251 = 31476312
73 + 31476239 = 31476312
163 + 31476149 = 31476312
193 + 31476119 = 31476312
199 + 31476113 = 31476312
239 + 31476073 = 31476312
281 + 31476031 = 31476312

Showing the first eight; more decompositions exist.
