Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502876, here are decompositions:

19 + 31502857 = 31502876
313 + 31502563 = 31502876
337 + 31502539 = 31502876
523 + 31502353 = 31502876
547 + 31502329 = 31502876
607 + 31502269 = 31502876
919 + 31501957 = 31502876
997 + 31501879 = 31502876

Showing the first eight; more decompositions exist.
