Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87074, here are decompositions:

3 + 87071 = 87074
37 + 87037 = 87074
61 + 87013 = 87074
151 + 86923 = 87074
223 + 86851 = 87074
307 + 86767 = 87074
331 + 86743 = 87074
397 + 86677 = 87074

Showing the first eight; more decompositions exist.
