Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156510, here are decompositions:

17 + 156493 = 156510
19 + 156491 = 156510
23 + 156487 = 156510
43 + 156467 = 156510
73 + 156437 = 156510
89 + 156421 = 156510
139 + 156371 = 156510
149 + 156361 = 156510

Showing the first eight; more decompositions exist.
