Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592072, here are decompositions:

19 + 31592053 = 31592072
73 + 31591999 = 31592072
79 + 31591993 = 31592072
163 + 31591909 = 31592072
199 + 31591873 = 31592072
229 + 31591843 = 31592072
349 + 31591723 = 31592072
619 + 31591453 = 31592072

Showing the first eight; more decompositions exist.
