Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595576, here are decompositions:

3 + 31595573 = 31595576
7 + 31595569 = 31595576
109 + 31595467 = 31595576
193 + 31595383 = 31595576
367 + 31595209 = 31595576
577 + 31594999 = 31595576
613 + 31594963 = 31595576
673 + 31594903 = 31595576

Showing the first eight; more decompositions exist.
