Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149130, here are decompositions:

11 + 149119 = 149130
17 + 149113 = 149130
19 + 149111 = 149130
29 + 149101 = 149130
31 + 149099 = 149130
43 + 149087 = 149130
53 + 149077 = 149130
61 + 149069 = 149130

Showing the first eight; more decompositions exist.
