Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537414, here are decompositions:

5 + 31537409 = 31537414
23 + 31537391 = 31537414
101 + 31537313 = 31537414
107 + 31537307 = 31537414
191 + 31537223 = 31537414
263 + 31537151 = 31537414
281 + 31537133 = 31537414
317 + 31537097 = 31537414

Showing the first eight; more decompositions exist.
