Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118512, here are decompositions:

19 + 118493 = 118512
41 + 118471 = 118512
59 + 118453 = 118512
83 + 118429 = 118512
89 + 118423 = 118512
101 + 118411 = 118512
103 + 118409 = 118512
113 + 118399 = 118512

Showing the first eight; more decompositions exist.
