Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143490, here are decompositions:

7 + 143483 = 143490
13 + 143477 = 143490
23 + 143467 = 143490
29 + 143461 = 143490
47 + 143443 = 143490
71 + 143419 = 143490
89 + 143401 = 143490
103 + 143387 = 143490

Showing the first eight; more decompositions exist.
