Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475048, here are decompositions:

19 + 31475029 = 31475048
67 + 31474981 = 31475048
79 + 31474969 = 31475048
181 + 31474867 = 31475048
271 + 31474777 = 31475048
379 + 31474669 = 31475048
499 + 31474549 = 31475048
547 + 31474501 = 31475048

Showing the first eight; more decompositions exist.
