Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144020, here are decompositions:

7 + 144013 = 144020
43 + 143977 = 144020
67 + 143953 = 144020
73 + 143947 = 144020
139 + 143881 = 144020
193 + 143827 = 144020
199 + 143821 = 144020
223 + 143797 = 144020

Showing the first eight; more decompositions exist.
