Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40130, here are decompositions:

3 + 40127 = 40130
7 + 40123 = 40130
19 + 40111 = 40130
31 + 40099 = 40130
37 + 40093 = 40130
43 + 40087 = 40130
67 + 40063 = 40130
151 + 39979 = 40130

Showing the first eight; more decompositions exist.
