Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85970, here are decompositions:

37 + 85933 = 85970
61 + 85909 = 85970
67 + 85903 = 85970
127 + 85843 = 85970
139 + 85831 = 85970
151 + 85819 = 85970
331 + 85639 = 85970
349 + 85621 = 85970

Showing the first eight; more decompositions exist.
