Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519048, here are decompositions:

59 + 31518989 = 31519048
149 + 31518899 = 31519048
167 + 31518881 = 31519048
179 + 31518869 = 31519048
269 + 31518779 = 31519048
389 + 31518659 = 31519048
401 + 31518647 = 31519048
557 + 31518491 = 31519048

Showing the first eight; more decompositions exist.
