Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592630, here are decompositions:

31 + 31592599 = 31592630
73 + 31592557 = 31592630
79 + 31592551 = 31592630
163 + 31592467 = 31592630
193 + 31592437 = 31592630
241 + 31592389 = 31592630
283 + 31592347 = 31592630
373 + 31592257 = 31592630

Showing the first eight; more decompositions exist.
