Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537410, here are decompositions:

19 + 31537391 = 31537410
71 + 31537339 = 31537410
83 + 31537327 = 31537410
97 + 31537313 = 31537410
101 + 31537309 = 31537410
103 + 31537307 = 31537410
137 + 31537273 = 31537410
139 + 31537271 = 31537410

Showing the first eight; more decompositions exist.
