Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592348, here are decompositions:

37 + 31592311 = 31592348
199 + 31592149 = 31592348
349 + 31591999 = 31592348
439 + 31591909 = 31592348
661 + 31591687 = 31592348
751 + 31591597 = 31592348
811 + 31591537 = 31592348
967 + 31591381 = 31592348

Showing the first eight; more decompositions exist.
