Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153430, here are decompositions:

3 + 153427 = 153430
23 + 153407 = 153430
59 + 153371 = 153430
71 + 153359 = 153430
149 + 153281 = 153430
239 + 153191 = 153430
293 + 153137 = 153430
317 + 153113 = 153430

Showing the first eight; more decompositions exist.
