Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537260, here are decompositions:

17 + 31537243 = 31537260
31 + 31537229 = 31537260
37 + 31537223 = 31537260
59 + 31537201 = 31537260
107 + 31537153 = 31537260
109 + 31537151 = 31537260
113 + 31537147 = 31537260
127 + 31537133 = 31537260

Showing the first eight; more decompositions exist.
