Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120618, here are decompositions:

11 + 120607 = 120618
31 + 120587 = 120618
41 + 120577 = 120618
61 + 120557 = 120618
67 + 120551 = 120618
79 + 120539 = 120618
107 + 120511 = 120618
191 + 120427 = 120618

Showing the first eight; more decompositions exist.
