Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590734, here are decompositions:

3 + 31590731 = 31590734
67 + 31590667 = 31590734
103 + 31590631 = 31590734
151 + 31590583 = 31590734
163 + 31590571 = 31590734
271 + 31590463 = 31590734
283 + 31590451 = 31590734
313 + 31590421 = 31590734

Showing the first eight; more decompositions exist.
