Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592592, here are decompositions:

41 + 31592551 = 31592592
61 + 31592531 = 31592592
103 + 31592489 = 31592592
139 + 31592453 = 31592592
181 + 31592411 = 31592592
223 + 31592369 = 31592592
281 + 31592311 = 31592592
373 + 31592219 = 31592592

Showing the first eight; more decompositions exist.
