Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592636, here are decompositions:

37 + 31592599 = 31592636
79 + 31592557 = 31592636
199 + 31592437 = 31592636
379 + 31592257 = 31592636
433 + 31592203 = 31592636
463 + 31592173 = 31592636
487 + 31592149 = 31592636
643 + 31591993 = 31592636

Showing the first eight; more decompositions exist.
