Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592918, here are decompositions:

109 + 31592809 = 31592918
139 + 31592779 = 31592918
157 + 31592761 = 31592918
241 + 31592677 = 31592918
277 + 31592641 = 31592918
367 + 31592551 = 31592918
541 + 31592377 = 31592918
571 + 31592347 = 31592918

Showing the first eight; more decompositions exist.
