Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590456, here are decompositions:

5 + 31590451 = 31590456
13 + 31590443 = 31590456
43 + 31590413 = 31590456
59 + 31590397 = 31590456
103 + 31590353 = 31590456
113 + 31590343 = 31590456
179 + 31590277 = 31590456
193 + 31590263 = 31590456

Showing the first eight; more decompositions exist.
