Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592456, here are decompositions:

3 + 31592453 = 31592456
19 + 31592437 = 31592456
67 + 31592389 = 31592456
79 + 31592377 = 31592456
109 + 31592347 = 31592456
199 + 31592257 = 31592456
283 + 31592173 = 31592456
307 + 31592149 = 31592456

Showing the first eight; more decompositions exist.
