Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590462, here are decompositions:

11 + 31590451 = 31590462
19 + 31590443 = 31590462
41 + 31590421 = 31590462
61 + 31590401 = 31590462
109 + 31590353 = 31590462
149 + 31590313 = 31590462
193 + 31590269 = 31590462
199 + 31590263 = 31590462

Showing the first eight; more decompositions exist.
