Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501084, here are decompositions:

3 + 31501081 = 31501084
23 + 31501061 = 31501084
47 + 31501037 = 31501084
107 + 31500977 = 31501084
137 + 31500947 = 31501084
311 + 31500773 = 31501084
317 + 31500767 = 31501084
347 + 31500737 = 31501084

Showing the first eight; more decompositions exist.
