Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120906, here are decompositions:

7 + 120899 = 120906
17 + 120889 = 120906
29 + 120877 = 120906
43 + 120863 = 120906
59 + 120847 = 120906
73 + 120833 = 120906
83 + 120823 = 120906
89 + 120817 = 120906

Showing the first eight; more decompositions exist.
