Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517602, here are decompositions:

5 + 31517597 = 31517602
23 + 31517579 = 31517602
29 + 31517573 = 31517602
59 + 31517543 = 31517602
101 + 31517501 = 31517602
191 + 31517411 = 31517602
359 + 31517243 = 31517602
563 + 31517039 = 31517602

Showing the first eight; more decompositions exist.
