Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517846, here are decompositions:

97 + 31517749 = 31517846
193 + 31517653 = 31517846
229 + 31517617 = 31517846
313 + 31517533 = 31517846
379 + 31517467 = 31517846
433 + 31517413 = 31517846
439 + 31517407 = 31517846
457 + 31517389 = 31517846

Showing the first eight; more decompositions exist.
