Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130618, here are decompositions:

29 + 130589 = 130618
71 + 130547 = 130618
101 + 130517 = 130618
149 + 130469 = 130618
179 + 130439 = 130618
239 + 130379 = 130618
251 + 130367 = 130618
269 + 130349 = 130618

Showing the first eight; more decompositions exist.
