Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147618, here are decompositions:

5 + 147613 = 147618
11 + 147607 = 147618
47 + 147571 = 147618
61 + 147557 = 147618
67 + 147551 = 147618
71 + 147547 = 147618
101 + 147517 = 147618
131 + 147487 = 147618

Showing the first eight; more decompositions exist.
