Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537714, here are decompositions:

23 + 31537691 = 31537714
83 + 31537631 = 31537714
167 + 31537547 = 31537714
233 + 31537481 = 31537714
281 + 31537433 = 31537714
401 + 31537313 = 31537714
443 + 31537271 = 31537714
491 + 31537223 = 31537714

Showing the first eight; more decompositions exist.
