Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592966, here are decompositions:

7 + 31592959 = 31592966
19 + 31592947 = 31592966
43 + 31592923 = 31592966
157 + 31592809 = 31592966
193 + 31592773 = 31592966
283 + 31592683 = 31592966
367 + 31592599 = 31592966
409 + 31592557 = 31592966

Showing the first eight; more decompositions exist.
