Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153618, here are decompositions:

7 + 153611 = 153618
11 + 153607 = 153618
29 + 153589 = 153618
61 + 153557 = 153618
89 + 153529 = 153618
97 + 153521 = 153618
107 + 153511 = 153618
109 + 153509 = 153618

Showing the first eight; more decompositions exist.
