Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156402, here are decompositions:

31 + 156371 = 156402
41 + 156361 = 156402
73 + 156329 = 156402
83 + 156319 = 156402
149 + 156253 = 156402
173 + 156229 = 156402
251 + 156151 = 156402
263 + 156139 = 156402

Showing the first eight; more decompositions exist.
