Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450012, here are decompositions:

23 + 31449989 = 31450012
89 + 31449923 = 31450012
311 + 31449701 = 31450012
383 + 31449629 = 31450012
401 + 31449611 = 31450012
431 + 31449581 = 31450012
443 + 31449569 = 31450012
563 + 31449449 = 31450012

Showing the first eight; more decompositions exist.
