Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149190, here are decompositions:

7 + 149183 = 149190
17 + 149173 = 149190
29 + 149161 = 149190
31 + 149159 = 149190
37 + 149153 = 149190
47 + 149143 = 149190
71 + 149119 = 149190
79 + 149111 = 149190

Showing the first eight; more decompositions exist.
