Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501766, here are decompositions:

7 + 31501759 = 31501766
67 + 31501699 = 31501766
97 + 31501669 = 31501766
199 + 31501567 = 31501766
229 + 31501537 = 31501766
367 + 31501399 = 31501766
379 + 31501387 = 31501766
433 + 31501333 = 31501766

Showing the first eight; more decompositions exist.
