Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517544, here are decompositions:

11 + 31517533 = 31517544
17 + 31517527 = 31517544
43 + 31517501 = 31517544
53 + 31517491 = 31517544
103 + 31517441 = 31517544
127 + 31517417 = 31517544
131 + 31517413 = 31517544
137 + 31517407 = 31517544

Showing the first eight; more decompositions exist.
