Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517104, here are decompositions:

41 + 31517063 = 31517104
83 + 31517021 = 31517104
131 + 31516973 = 31517104
263 + 31516841 = 31517104
293 + 31516811 = 31517104
317 + 31516787 = 31517104
347 + 31516757 = 31517104
401 + 31516703 = 31517104

Showing the first eight; more decompositions exist.
