Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489446, here are decompositions:

13 + 31489433 = 31489446
19 + 31489427 = 31489446
29 + 31489417 = 31489446
47 + 31489399 = 31489446
83 + 31489363 = 31489446
97 + 31489349 = 31489446
167 + 31489279 = 31489446
199 + 31489247 = 31489446

Showing the first eight; more decompositions exist.
