Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517548, here are decompositions:

5 + 31517543 = 31517548
47 + 31517501 = 31517548
107 + 31517441 = 31517548
131 + 31517417 = 31517548
137 + 31517411 = 31517548
149 + 31517399 = 31517548
281 + 31517267 = 31517548
317 + 31517231 = 31517548

Showing the first eight; more decompositions exist.
