Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476154, here are decompositions:

5 + 31476149 = 31476154
11 + 31476143 = 31476154
41 + 31476113 = 31476154
137 + 31476017 = 31476154
191 + 31475963 = 31476154
383 + 31475771 = 31476154
557 + 31475597 = 31476154
683 + 31475471 = 31476154

Showing the first eight; more decompositions exist.
