Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144390, here are decompositions:

7 + 144383 = 144390
11 + 144379 = 144390
41 + 144349 = 144390
67 + 144323 = 144390
79 + 144311 = 144390
83 + 144307 = 144390
101 + 144289 = 144390
131 + 144259 = 144390

Showing the first eight; more decompositions exist.
