Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156450, here are decompositions:

13 + 156437 = 156450
29 + 156421 = 156450
31 + 156419 = 156450
79 + 156371 = 156450
89 + 156361 = 156450
97 + 156353 = 156450
103 + 156347 = 156450
131 + 156319 = 156450

Showing the first eight; more decompositions exist.
