Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120870, here are decompositions:

7 + 120863 = 120870
19 + 120851 = 120870
23 + 120847 = 120870
37 + 120833 = 120870
41 + 120829 = 120870
47 + 120823 = 120870
53 + 120817 = 120870
59 + 120811 = 120870

Showing the first eight; more decompositions exist.
