Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465648, here are decompositions:

17 + 31465631 = 31465648
29 + 31465619 = 31465648
47 + 31465601 = 31465648
101 + 31465547 = 31465648
167 + 31465481 = 31465648
197 + 31465451 = 31465648
257 + 31465391 = 31465648
359 + 31465289 = 31465648

Showing the first eight; more decompositions exist.
