Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537654, here are decompositions:

23 + 31537631 = 31537654
107 + 31537547 = 31537654
173 + 31537481 = 31537654
263 + 31537391 = 31537654
347 + 31537307 = 31537654
383 + 31537271 = 31537654
431 + 31537223 = 31537654
503 + 31537151 = 31537654

Showing the first eight; more decompositions exist.
