Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592450, here are decompositions:

3 + 31592447 = 31592450
13 + 31592437 = 31592450
61 + 31592389 = 31592450
73 + 31592377 = 31592450
103 + 31592347 = 31592450
139 + 31592311 = 31592450
193 + 31592257 = 31592450
277 + 31592173 = 31592450

Showing the first eight; more decompositions exist.
