Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42802, here are decompositions:

5 + 42797 = 42802
29 + 42773 = 42802
59 + 42743 = 42802
83 + 42719 = 42802
101 + 42701 = 42802
113 + 42689 = 42802
191 + 42611 = 42802
233 + 42569 = 42802

Showing the first eight; more decompositions exist.
