Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592994, here are decompositions:

11 + 31592983 = 31592994
23 + 31592971 = 31592994
47 + 31592947 = 31592994
71 + 31592923 = 31592994
73 + 31592921 = 31592994
151 + 31592843 = 31592994
197 + 31592797 = 31592994
233 + 31592761 = 31592994

Showing the first eight; more decompositions exist.
