Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592756, here are decompositions:

73 + 31592683 = 31592756
79 + 31592677 = 31592756
157 + 31592599 = 31592756
199 + 31592557 = 31592756
367 + 31592389 = 31592756
379 + 31592377 = 31592756
409 + 31592347 = 31592756
499 + 31592257 = 31592756

Showing the first eight; more decompositions exist.
