Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144090, here are decompositions:

17 + 144073 = 144090
19 + 144071 = 144090
29 + 144061 = 144090
53 + 144037 = 144090
59 + 144031 = 144090
109 + 143981 = 144090
113 + 143977 = 144090
137 + 143953 = 144090

Showing the first eight; more decompositions exist.
