Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151508, here are decompositions:

31 + 151477 = 151508
37 + 151471 = 151508
79 + 151429 = 151508
127 + 151381 = 151508
151 + 151357 = 151508
229 + 151279 = 151508
271 + 151237 = 151508
307 + 151201 = 151508

Showing the first eight; more decompositions exist.
