Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590736, here are decompositions:

3 + 31590733 = 31590736
5 + 31590731 = 31590736
53 + 31590683 = 31590736
179 + 31590557 = 31590736
257 + 31590479 = 31590736
269 + 31590467 = 31590736
293 + 31590443 = 31590736
383 + 31590353 = 31590736

Showing the first eight; more decompositions exist.
