Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592948, here are decompositions:

139 + 31592809 = 31592948
151 + 31592797 = 31592948
271 + 31592677 = 31592948
307 + 31592641 = 31592948
349 + 31592599 = 31592948
397 + 31592551 = 31592948
571 + 31592377 = 31592948
601 + 31592347 = 31592948

Showing the first eight; more decompositions exist.
