Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151450, here are decompositions:

17 + 151433 = 151450
53 + 151397 = 151450
59 + 151391 = 151450
71 + 151379 = 151450
107 + 151343 = 151450
113 + 151337 = 151450
197 + 151253 = 151450
281 + 151169 = 151450

Showing the first eight; more decompositions exist.
