Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517632, here are decompositions:

53 + 31517579 = 31517632
59 + 31517573 = 31517632
89 + 31517543 = 31517632
131 + 31517501 = 31517632
191 + 31517441 = 31517632
233 + 31517399 = 31517632
239 + 31517393 = 31517632
359 + 31517273 = 31517632

Showing the first eight; more decompositions exist.
