Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537546, here are decompositions:

3 + 31537543 = 31537546
113 + 31537433 = 31537546
137 + 31537409 = 31537546
233 + 31537313 = 31537546
239 + 31537307 = 31537546
317 + 31537229 = 31537546
419 + 31537127 = 31537546
449 + 31537097 = 31537546

Showing the first eight; more decompositions exist.
