Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590746, here are decompositions:

7 + 31590739 = 31590746
13 + 31590733 = 31590746
79 + 31590667 = 31590746
97 + 31590649 = 31590746
157 + 31590589 = 31590746
163 + 31590583 = 31590746
277 + 31590469 = 31590746
283 + 31590463 = 31590746

Showing the first eight; more decompositions exist.
