Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575592, here are decompositions:

29 + 31575563 = 31575592
71 + 31575521 = 31575592
239 + 31575353 = 31575592
281 + 31575311 = 31575592
311 + 31575281 = 31575592
359 + 31575233 = 31575592
431 + 31575161 = 31575592
593 + 31574999 = 31575592

Showing the first eight; more decompositions exist.
