Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537374, here are decompositions:

47 + 31537327 = 31537374
61 + 31537313 = 31537374
67 + 31537307 = 31537374
101 + 31537273 = 31537374
103 + 31537271 = 31537374
107 + 31537267 = 31537374
131 + 31537243 = 31537374
151 + 31537223 = 31537374

Showing the first eight; more decompositions exist.
