Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591482, here are decompositions:

5 + 31591477 = 31591482
29 + 31591453 = 31591482
61 + 31591421 = 31591482
73 + 31591409 = 31591482
101 + 31591381 = 31591482
151 + 31591331 = 31591482
191 + 31591291 = 31591482
233 + 31591249 = 31591482

Showing the first eight; more decompositions exist.
