Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153390, here are decompositions:

11 + 153379 = 153390
19 + 153371 = 153390
31 + 153359 = 153390
37 + 153353 = 153390
47 + 153343 = 153390
53 + 153337 = 153390
71 + 153319 = 153390
103 + 153287 = 153390

Showing the first eight; more decompositions exist.
