Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613454, here are decompositions:

13 + 31613441 = 31613454
17 + 31613437 = 31613454
43 + 31613411 = 31613454
53 + 31613401 = 31613454
71 + 31613383 = 31613454
97 + 31613357 = 31613454
113 + 31613341 = 31613454
163 + 31613291 = 31613454

Showing the first eight; more decompositions exist.
