Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609076, here are decompositions:

43 + 31609033 = 31609076
139 + 31608937 = 31609076
193 + 31608883 = 31609076
223 + 31608853 = 31609076
283 + 31608793 = 31609076
349 + 31608727 = 31609076
379 + 31608697 = 31609076
409 + 31608667 = 31609076

Showing the first eight; more decompositions exist.
