Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476146, here are decompositions:

3 + 31476143 = 31476146
73 + 31476073 = 31476146
193 + 31475953 = 31476146
349 + 31475797 = 31476146
367 + 31475779 = 31476146
397 + 31475749 = 31476146
433 + 31475713 = 31476146
463 + 31475683 = 31476146

Showing the first eight; more decompositions exist.
