Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588482, here are decompositions:

11 + 31588471 = 31588482
19 + 31588463 = 31588482
41 + 31588441 = 31588482
43 + 31588439 = 31588482
83 + 31588399 = 31588482
113 + 31588369 = 31588482
131 + 31588351 = 31588482
151 + 31588331 = 31588482

Showing the first eight; more decompositions exist.
