Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144488, here are decompositions:

7 + 144481 = 144488
37 + 144451 = 144488
61 + 144427 = 144488
79 + 144409 = 144488
109 + 144379 = 144488
139 + 144349 = 144488
181 + 144307 = 144488
199 + 144289 = 144488

Showing the first eight; more decompositions exist.
