Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475632, here are decompositions:

53 + 31475579 = 31475632
173 + 31475459 = 31475632
179 + 31475453 = 31475632
239 + 31475393 = 31475632
311 + 31475321 = 31475632
389 + 31475243 = 31475632
401 + 31475231 = 31475632
443 + 31475189 = 31475632

Showing the first eight; more decompositions exist.
