Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602618, here are decompositions:

29 + 31602589 = 31602618
31 + 31602587 = 31602618
37 + 31602581 = 31602618
79 + 31602539 = 31602618
97 + 31602521 = 31602618
101 + 31602517 = 31602618
137 + 31602481 = 31602618
167 + 31602451 = 31602618

Showing the first eight; more decompositions exist.
