Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467412, here are decompositions:

23 + 31467389 = 31467412
83 + 31467329 = 31467412
101 + 31467311 = 31467412
401 + 31467011 = 31467412
419 + 31466993 = 31467412
443 + 31466969 = 31467412
461 + 31466951 = 31467412
479 + 31466933 = 31467412

Showing the first eight; more decompositions exist.
