Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65870, here are decompositions:

3 + 65867 = 65870
19 + 65851 = 65870
31 + 65839 = 65870
43 + 65827 = 65870
61 + 65809 = 65870
109 + 65761 = 65870
139 + 65731 = 65870
151 + 65719 = 65870

Showing the first eight; more decompositions exist.
