Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537392, here are decompositions:

53 + 31537339 = 31537392
79 + 31537313 = 31537392
83 + 31537309 = 31537392
149 + 31537243 = 31537392
163 + 31537229 = 31537392
191 + 31537201 = 31537392
239 + 31537153 = 31537392
241 + 31537151 = 31537392

Showing the first eight; more decompositions exist.
