Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609766, here are decompositions:

7 + 31609759 = 31609766
43 + 31609723 = 31609766
73 + 31609693 = 31609766
157 + 31609609 = 31609766
313 + 31609453 = 31609766
373 + 31609393 = 31609766
499 + 31609267 = 31609766
577 + 31609189 = 31609766

Showing the first eight; more decompositions exist.
