Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143430, here are decompositions:

11 + 143419 = 143430
17 + 143413 = 143430
29 + 143401 = 143430
43 + 143387 = 143430
73 + 143357 = 143430
97 + 143333 = 143430
101 + 143329 = 143430
139 + 143291 = 143430

Showing the first eight; more decompositions exist.
