Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007870, here are decompositions:

13 + 1007857 = 1007870
43 + 1007827 = 1007870
103 + 1007767 = 1007870
139 + 1007731 = 1007870
151 + 1007719 = 1007870
223 + 1007647 = 1007870
271 + 1007599 = 1007870
313 + 1007557 = 1007870

Showing the first eight; more decompositions exist.
