Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537492, here are decompositions:

11 + 31537481 = 31537492
23 + 31537469 = 31537492
59 + 31537433 = 31537492
83 + 31537409 = 31537492
101 + 31537391 = 31537492
179 + 31537313 = 31537492
263 + 31537229 = 31537492
269 + 31537223 = 31537492

Showing the first eight; more decompositions exist.
