Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592996, here are decompositions:

3 + 31592993 = 31592996
13 + 31592983 = 31592996
37 + 31592959 = 31592996
73 + 31592923 = 31592996
163 + 31592833 = 31592996
199 + 31592797 = 31592996
223 + 31592773 = 31592996
313 + 31592683 = 31592996

Showing the first eight; more decompositions exist.
