Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601078, here are decompositions:

37 + 31601041 = 31601078
109 + 31600969 = 31601078
277 + 31600801 = 31601078
307 + 31600771 = 31601078
337 + 31600741 = 31601078
409 + 31600669 = 31601078
547 + 31600531 = 31601078
631 + 31600447 = 31601078

Showing the first eight; more decompositions exist.
