Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476202, here are decompositions:

53 + 31476149 = 31476202
59 + 31476143 = 31476202
83 + 31476119 = 31476202
89 + 31476113 = 31476202
239 + 31475963 = 31476202
293 + 31475909 = 31476202
353 + 31475849 = 31476202
389 + 31475813 = 31476202

Showing the first eight; more decompositions exist.
