Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517404, here are decompositions:

5 + 31517399 = 31517404
11 + 31517393 = 31517404
131 + 31517273 = 31517404
137 + 31517267 = 31517404
173 + 31517231 = 31517404
197 + 31517207 = 31517404
383 + 31517021 = 31517404
431 + 31516973 = 31517404

Showing the first eight; more decompositions exist.
