Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144836, here are decompositions:

7 + 144829 = 144836
19 + 144817 = 144836
73 + 144763 = 144836
79 + 144757 = 144836
127 + 144709 = 144836
397 + 144439 = 144836
409 + 144427 = 144836
457 + 144379 = 144836

Showing the first eight; more decompositions exist.
