Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537370, here are decompositions:

31 + 31537339 = 31537370
43 + 31537327 = 31537370
61 + 31537309 = 31537370
97 + 31537273 = 31537370
103 + 31537267 = 31537370
127 + 31537243 = 31537370
223 + 31537147 = 31537370
283 + 31537087 = 31537370

Showing the first eight; more decompositions exist.
