Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502012, here are decompositions:

151 + 31501861 = 31502012
163 + 31501849 = 31502012
181 + 31501831 = 31502012
193 + 31501819 = 31502012
271 + 31501741 = 31502012
313 + 31501699 = 31502012
379 + 31501633 = 31502012
613 + 31501399 = 31502012

Showing the first eight; more decompositions exist.
