Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591484, here are decompositions:

7 + 31591477 = 31591484
31 + 31591453 = 31591484
37 + 31591447 = 31591484
103 + 31591381 = 31591484
193 + 31591291 = 31591484
277 + 31591207 = 31591484
307 + 31591177 = 31591484
313 + 31591171 = 31591484

Showing the first eight; more decompositions exist.
