Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146130, here are decompositions:

13 + 146117 = 146130
31 + 146099 = 146130
37 + 146093 = 146130
53 + 146077 = 146130
67 + 146063 = 146130
71 + 146059 = 146130
73 + 146057 = 146130
79 + 146051 = 146130

Showing the first eight; more decompositions exist.
