Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475564, here are decompositions:

73 + 31475491 = 31475564
157 + 31475407 = 31475564
163 + 31475401 = 31475564
193 + 31475371 = 31475564
223 + 31475341 = 31475564
277 + 31475287 = 31475564
313 + 31475251 = 31475564
433 + 31475131 = 31475564

Showing the first eight; more decompositions exist.
