Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592744, here are decompositions:

61 + 31592683 = 31592744
67 + 31592677 = 31592744
103 + 31592641 = 31592744
193 + 31592551 = 31592744
277 + 31592467 = 31592744
307 + 31592437 = 31592744
367 + 31592377 = 31592744
397 + 31592347 = 31592744

Showing the first eight; more decompositions exist.
