Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147540, here are decompositions:

23 + 147517 = 147540
37 + 147503 = 147540
53 + 147487 = 147540
59 + 147481 = 147540
83 + 147457 = 147540
89 + 147451 = 147540
131 + 147409 = 147540
139 + 147401 = 147540

Showing the first eight; more decompositions exist.
