Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537822, here are decompositions:

101 + 31537721 = 31537822
131 + 31537691 = 31537822
191 + 31537631 = 31537822
263 + 31537559 = 31537822
353 + 31537469 = 31537822
389 + 31537433 = 31537822
431 + 31537391 = 31537822
509 + 31537313 = 31537822

Showing the first eight; more decompositions exist.
