Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590752, here are decompositions:

13 + 31590739 = 31590752
19 + 31590733 = 31590752
103 + 31590649 = 31590752
163 + 31590589 = 31590752
181 + 31590571 = 31590752
283 + 31590469 = 31590752
331 + 31590421 = 31590752
409 + 31590343 = 31590752

Showing the first eight; more decompositions exist.
