Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28602, here are decompositions:

5 + 28597 = 28602
11 + 28591 = 28602
23 + 28579 = 28602
29 + 28573 = 28602
31 + 28571 = 28602
43 + 28559 = 28602
53 + 28549 = 28602
61 + 28541 = 28602

Showing the first eight; more decompositions exist.
