Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475774, here are decompositions:

3 + 31475771 = 31475774
61 + 31475713 = 31475774
97 + 31475677 = 31475774
151 + 31475623 = 31475774
163 + 31475611 = 31475774
193 + 31475581 = 31475774
283 + 31475491 = 31475774
331 + 31475443 = 31475774

Showing the first eight; more decompositions exist.
