Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591362, here are decompositions:

13 + 31591349 = 31591362
31 + 31591331 = 31591362
71 + 31591291 = 31591362
113 + 31591249 = 31591362
163 + 31591199 = 31591362
191 + 31591171 = 31591362
263 + 31591099 = 31591362
269 + 31591093 = 31591362

Showing the first eight; more decompositions exist.
