Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592240, here are decompositions:

37 + 31592203 = 31592240
67 + 31592173 = 31592240
79 + 31592161 = 31592240
193 + 31592047 = 31592240
241 + 31591999 = 31592240
283 + 31591957 = 31592240
331 + 31591909 = 31592240
367 + 31591873 = 31592240

Showing the first eight; more decompositions exist.
