Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146040, here are decompositions:

7 + 146033 = 146040
17 + 146023 = 146040
19 + 146021 = 146040
29 + 146011 = 146040
31 + 146009 = 146040
53 + 145987 = 146040
71 + 145969 = 146040
73 + 145967 = 146040

Showing the first eight; more decompositions exist.
