Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524848, here are decompositions:

127 + 31524721 = 31524848
241 + 31524607 = 31524848
307 + 31524541 = 31524848
331 + 31524517 = 31524848
349 + 31524499 = 31524848
379 + 31524469 = 31524848
547 + 31524301 = 31524848
571 + 31524277 = 31524848

Showing the first eight; more decompositions exist.
