Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537446, here are decompositions:

13 + 31537433 = 31537446
37 + 31537409 = 31537446
107 + 31537339 = 31537446
137 + 31537309 = 31537446
139 + 31537307 = 31537446
173 + 31537273 = 31537446
179 + 31537267 = 31537446
223 + 31537223 = 31537446

Showing the first eight; more decompositions exist.
