Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502526, here are decompositions:

37 + 31502489 = 31502526
43 + 31502483 = 31502526
67 + 31502459 = 31502526
163 + 31502363 = 31502526
173 + 31502353 = 31502526
193 + 31502333 = 31502526
197 + 31502329 = 31502526
239 + 31502287 = 31502526

Showing the first eight; more decompositions exist.
