Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101802, here are decompositions:

5 + 101797 = 101802
13 + 101789 = 101802
31 + 101771 = 101802
53 + 101749 = 101802
61 + 101741 = 101802
79 + 101723 = 101802
83 + 101719 = 101802
101 + 101701 = 101802

Showing the first eight; more decompositions exist.
