Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153012, here are decompositions:

11 + 153001 = 153012
19 + 152993 = 153012
23 + 152989 = 153012
31 + 152981 = 153012
53 + 152959 = 153012
59 + 152953 = 153012
71 + 152941 = 153012
73 + 152939 = 153012

Showing the first eight; more decompositions exist.
