Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574894, here are decompositions:

3 + 31574891 = 31574894
7 + 31574887 = 31574894
31 + 31574863 = 31574894
73 + 31574821 = 31574894
193 + 31574701 = 31574894
223 + 31574671 = 31574894
331 + 31574563 = 31574894
397 + 31574497 = 31574894

Showing the first eight; more decompositions exist.
