Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151548, here are decompositions:

11 + 151537 = 151548
17 + 151531 = 151548
31 + 151517 = 151548
41 + 151507 = 151548
71 + 151477 = 151548
97 + 151451 = 151548
151 + 151397 = 151548
157 + 151391 = 151548

Showing the first eight; more decompositions exist.
