Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017860, here are decompositions:

3 + 1017857 = 1017860
13 + 1017847 = 1017860
43 + 1017817 = 1017860
61 + 1017799 = 1017860
73 + 1017787 = 1017860
79 + 1017781 = 1017860
139 + 1017721 = 1017860
157 + 1017703 = 1017860

Showing the first eight; more decompositions exist.
