Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475516, here are decompositions:

73 + 31475443 = 31475516
109 + 31475407 = 31475516
199 + 31475317 = 31475516
229 + 31475287 = 31475516
307 + 31475209 = 31475516
409 + 31475107 = 31475516
433 + 31475083 = 31475516
463 + 31475053 = 31475516

Showing the first eight; more decompositions exist.
