Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592962, here are decompositions:

3 + 31592959 = 31592962
41 + 31592921 = 31592962
113 + 31592849 = 31592962
311 + 31592651 = 31592962
431 + 31592531 = 31592962
509 + 31592453 = 31592962
593 + 31592369 = 31592962
743 + 31592219 = 31592962

Showing the first eight; more decompositions exist.
