Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151448, here are decompositions:

19 + 151429 = 151448
67 + 151381 = 151448
109 + 151339 = 151448
211 + 151237 = 151448
277 + 151171 = 151448
307 + 151141 = 151448
397 + 151051 = 151448
421 + 151027 = 151448

Showing the first eight; more decompositions exist.
