Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502122, here are decompositions:

23 + 31502099 = 31502122
401 + 31501721 = 31502122
461 + 31501661 = 31502122
503 + 31501619 = 31502122
599 + 31501523 = 31502122
719 + 31501403 = 31502122
761 + 31501361 = 31502122
809 + 31501313 = 31502122

Showing the first eight; more decompositions exist.
