Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144998, here are decompositions:

31 + 144967 = 144998
37 + 144961 = 144998
67 + 144931 = 144998
109 + 144889 = 144998
151 + 144847 = 144998
181 + 144817 = 144998
241 + 144757 = 144998
331 + 144667 = 144998

Showing the first eight; more decompositions exist.
