Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537346, here are decompositions:

7 + 31537339 = 31537346
19 + 31537327 = 31537346
37 + 31537309 = 31537346
73 + 31537273 = 31537346
79 + 31537267 = 31537346
103 + 31537243 = 31537346
193 + 31537153 = 31537346
199 + 31537147 = 31537346

Showing the first eight; more decompositions exist.
