Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144678, here are decompositions:

7 + 144671 = 144678
11 + 144667 = 144678
19 + 144659 = 144678
67 + 144611 = 144678
89 + 144589 = 144678
101 + 144577 = 144678
109 + 144569 = 144678
137 + 144541 = 144678

Showing the first eight; more decompositions exist.
