Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592834, here are decompositions:

37 + 31592797 = 31592834
61 + 31592773 = 31592834
73 + 31592761 = 31592834
151 + 31592683 = 31592834
157 + 31592677 = 31592834
193 + 31592641 = 31592834
277 + 31592557 = 31592834
283 + 31592551 = 31592834

Showing the first eight; more decompositions exist.
