Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102236, here are decompositions:

3 + 102233 = 102236
7 + 102229 = 102236
19 + 102217 = 102236
37 + 102199 = 102236
97 + 102139 = 102236
157 + 102079 = 102236
193 + 102043 = 102236
223 + 102013 = 102236

Showing the first eight; more decompositions exist.
