Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499454, here are decompositions:

23 + 31499431 = 31499454
43 + 31499411 = 31499454
47 + 31499407 = 31499454
53 + 31499401 = 31499454
67 + 31499387 = 31499454
71 + 31499383 = 31499454
83 + 31499371 = 31499454
113 + 31499341 = 31499454

Showing the first eight; more decompositions exist.
