Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145848, here are decompositions:

19 + 145829 = 145848
29 + 145819 = 145848
41 + 145807 = 145848
71 + 145777 = 145848
89 + 145759 = 145848
127 + 145721 = 145848
139 + 145709 = 145848
167 + 145681 = 145848

Showing the first eight; more decompositions exist.
