Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537462, here are decompositions:

29 + 31537433 = 31537462
53 + 31537409 = 31537462
71 + 31537391 = 31537462
149 + 31537313 = 31537462
191 + 31537271 = 31537462
233 + 31537229 = 31537462
239 + 31537223 = 31537462
311 + 31537151 = 31537462

Showing the first eight; more decompositions exist.
