Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501134, here are decompositions:

17 + 31501117 = 31501134
43 + 31501091 = 31501134
53 + 31501081 = 31501134
73 + 31501061 = 31501134
97 + 31501037 = 31501134
157 + 31500977 = 31501134
167 + 31500967 = 31501134
193 + 31500941 = 31501134

Showing the first eight; more decompositions exist.
