Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537338, here are decompositions:

11 + 31537327 = 31537338
29 + 31537309 = 31537338
31 + 31537307 = 31537338
67 + 31537271 = 31537338
71 + 31537267 = 31537338
109 + 31537229 = 31537338
137 + 31537201 = 31537338
191 + 31537147 = 31537338

Showing the first eight; more decompositions exist.
