Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592984, here are decompositions:

13 + 31592971 = 31592984
37 + 31592947 = 31592984
61 + 31592923 = 31592984
151 + 31592833 = 31592984
211 + 31592773 = 31592984
223 + 31592761 = 31592984
307 + 31592677 = 31592984
433 + 31592551 = 31592984

Showing the first eight; more decompositions exist.
