Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502094, here are decompositions:

11 + 31502083 = 31502094
137 + 31501957 = 31502094
157 + 31501937 = 31502094
181 + 31501913 = 31502094
233 + 31501861 = 31502094
263 + 31501831 = 31502094
271 + 31501823 = 31502094
313 + 31501781 = 31502094

Showing the first eight; more decompositions exist.
