Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592540, here are decompositions:

73 + 31592467 = 31592540
103 + 31592437 = 31592540
151 + 31592389 = 31592540
163 + 31592377 = 31592540
193 + 31592347 = 31592540
229 + 31592311 = 31592540
283 + 31592257 = 31592540
337 + 31592203 = 31592540

Showing the first eight; more decompositions exist.
