Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517674, here are decompositions:

101 + 31517573 = 31517674
131 + 31517543 = 31517674
173 + 31517501 = 31517674
233 + 31517441 = 31517674
257 + 31517417 = 31517674
263 + 31517411 = 31517674
281 + 31517393 = 31517674
401 + 31517273 = 31517674

Showing the first eight; more decompositions exist.
