Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537702, here are decompositions:

11 + 31537691 = 31537702
71 + 31537631 = 31537702
233 + 31537469 = 31537702
269 + 31537433 = 31537702
293 + 31537409 = 31537702
311 + 31537391 = 31537702
389 + 31537313 = 31537702
431 + 31537271 = 31537702

Showing the first eight; more decompositions exist.
