Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602, here are decompositions:

19 + 31583 = 31602
29 + 31573 = 31602
59 + 31543 = 31602
61 + 31541 = 31602
71 + 31531 = 31602
89 + 31513 = 31602
113 + 31489 = 31602
211 + 31391 = 31602

Showing the first eight; more decompositions exist.
