Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002078, here are decompositions:

5 + 1002073 = 1002078
17 + 1002061 = 1002078
29 + 1002049 = 1002078
61 + 1002017 = 1002078
89 + 1001989 = 1002078
97 + 1001981 = 1002078
101 + 1001977 = 1002078
131 + 1001947 = 1002078

Showing the first eight; more decompositions exist.
