Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591596, here are decompositions:

19 + 31591577 = 31591596
59 + 31591537 = 31591596
79 + 31591517 = 31591596
83 + 31591513 = 31591596
97 + 31591499 = 31591596
103 + 31591493 = 31591596
149 + 31591447 = 31591596
229 + 31591367 = 31591596

Showing the first eight; more decompositions exist.
