Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143508, here are decompositions:

5 + 143503 = 143508
7 + 143501 = 143508
19 + 143489 = 143508
31 + 143477 = 143508
41 + 143467 = 143508
47 + 143461 = 143508
89 + 143419 = 143508
107 + 143401 = 143508

Showing the first eight; more decompositions exist.
