Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480024, here are decompositions:

3 + 31480021 = 31480024
5 + 31480019 = 31480024
167 + 31479857 = 31480024
281 + 31479743 = 31480024
353 + 31479671 = 31480024
431 + 31479593 = 31480024
467 + 31479557 = 31480024
557 + 31479467 = 31480024

Showing the first eight; more decompositions exist.
