Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501092, here are decompositions:

11 + 31501081 = 31501092
31 + 31501061 = 31501092
53 + 31501039 = 31501092
83 + 31501009 = 31501092
113 + 31500979 = 31501092
151 + 31500941 = 31501092
173 + 31500919 = 31501092
193 + 31500899 = 31501092

Showing the first eight; more decompositions exist.
