Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590792, here are decompositions:

29 + 31590763 = 31590792
53 + 31590739 = 31590792
59 + 31590733 = 31590792
61 + 31590731 = 31590792
109 + 31590683 = 31590792
199 + 31590593 = 31590792
241 + 31590551 = 31590792
293 + 31590499 = 31590792

Showing the first eight; more decompositions exist.
