Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609070, here are decompositions:

37 + 31609033 = 31609070
277 + 31608793 = 31609070
313 + 31608757 = 31609070
349 + 31608721 = 31609070
373 + 31608697 = 31609070
541 + 31608529 = 31609070
643 + 31608427 = 31609070
733 + 31608337 = 31609070

Showing the first eight; more decompositions exist.
