Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463430, here are decompositions:

23 + 31463407 = 31463430
41 + 31463389 = 31463430
43 + 31463387 = 31463430
67 + 31463363 = 31463430
101 + 31463329 = 31463430
109 + 31463321 = 31463430
113 + 31463317 = 31463430
149 + 31463281 = 31463430

Showing the first eight; more decompositions exist.
