Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002860, here are decompositions:

3 + 1002857 = 1002860
7 + 1002853 = 1002860
43 + 1002817 = 1002860
73 + 1002787 = 1002860
109 + 1002751 = 1002860
139 + 1002721 = 1002860
151 + 1002709 = 1002860
181 + 1002679 = 1002860

Showing the first eight; more decompositions exist.
