Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511914, here are decompositions:

23 + 31511891 = 31511914
41 + 31511873 = 31511914
47 + 31511867 = 31511914
101 + 31511813 = 31511914
113 + 31511801 = 31511914
263 + 31511651 = 31511914
431 + 31511483 = 31511914
443 + 31511471 = 31511914

Showing the first eight; more decompositions exist.
