Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517622, here are decompositions:

5 + 31517617 = 31517622
43 + 31517579 = 31517622
79 + 31517543 = 31517622
89 + 31517533 = 31517622
131 + 31517491 = 31517622
181 + 31517441 = 31517622
211 + 31517411 = 31517622
223 + 31517399 = 31517622

Showing the first eight; more decompositions exist.
