Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3618, here are decompositions:

5 + 3613 = 3618
11 + 3607 = 3618
37 + 3581 = 3618
47 + 3571 = 3618
59 + 3559 = 3618
61 + 3557 = 3618
71 + 3547 = 3618
79 + 3539 = 3618

Showing the first eight; more decompositions exist.
