Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143502, here are decompositions:

13 + 143489 = 143502
19 + 143483 = 143502
41 + 143461 = 143502
59 + 143443 = 143502
83 + 143419 = 143502
89 + 143413 = 143502
101 + 143401 = 143502
173 + 143329 = 143502

Showing the first eight; more decompositions exist.
