Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524920, here are decompositions:

127 + 31524793 = 31524920
157 + 31524763 = 31524920
199 + 31524721 = 31524920
277 + 31524643 = 31524920
313 + 31524607 = 31524920
379 + 31524541 = 31524920
397 + 31524523 = 31524920
421 + 31524499 = 31524920

Showing the first eight; more decompositions exist.
