Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501176, here are decompositions:

59 + 31501117 = 31501176
137 + 31501039 = 31501176
139 + 31501037 = 31501176
167 + 31501009 = 31501176
197 + 31500979 = 31501176
199 + 31500977 = 31501176
229 + 31500947 = 31501176
257 + 31500919 = 31501176

Showing the first eight; more decompositions exist.
