Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502060, here are decompositions:

103 + 31501957 = 31502060
181 + 31501879 = 31502060
199 + 31501861 = 31502060
211 + 31501849 = 31502060
229 + 31501831 = 31502060
241 + 31501819 = 31502060
439 + 31501621 = 31502060
523 + 31501537 = 31502060

Showing the first eight; more decompositions exist.
