Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28702, here are decompositions:

5 + 28697 = 28702
41 + 28661 = 28702
53 + 28649 = 28702
59 + 28643 = 28702
71 + 28631 = 28702
83 + 28619 = 28702
131 + 28571 = 28702
239 + 28463 = 28702

Showing the first eight; more decompositions exist.
