Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87122, here are decompositions:

3 + 87119 = 87122
19 + 87103 = 87122
73 + 87049 = 87122
109 + 87013 = 87122
163 + 86959 = 87122
193 + 86929 = 87122
199 + 86923 = 87122
271 + 86851 = 87122

Showing the first eight; more decompositions exist.
