Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517848, here are decompositions:

149 + 31517699 = 31517848
251 + 31517597 = 31517848
269 + 31517579 = 31517848
347 + 31517501 = 31517848
431 + 31517417 = 31517848
449 + 31517399 = 31517848
617 + 31517231 = 31517848
641 + 31517207 = 31517848

Showing the first eight; more decompositions exist.
