Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144428, here are decompositions:

19 + 144409 = 144428
79 + 144349 = 144428
139 + 144289 = 144428
157 + 144271 = 144428
181 + 144247 = 144428
367 + 144061 = 144428
397 + 144031 = 144428
457 + 143971 = 144428

Showing the first eight; more decompositions exist.
