Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517606, here are decompositions:

19 + 31517587 = 31517606
73 + 31517533 = 31517606
79 + 31517527 = 31517606
139 + 31517467 = 31517606
193 + 31517413 = 31517606
199 + 31517407 = 31517606
409 + 31517197 = 31517606
457 + 31517149 = 31517606

Showing the first eight; more decompositions exist.
