Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42618, here are decompositions:

7 + 42611 = 42618
29 + 42589 = 42618
41 + 42577 = 42618
47 + 42571 = 42618
61 + 42557 = 42618
109 + 42509 = 42618
127 + 42491 = 42618
131 + 42487 = 42618

Showing the first eight; more decompositions exist.
