Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144008, here are decompositions:

31 + 143977 = 144008
37 + 143971 = 144008
61 + 143947 = 144008
127 + 143881 = 144008
181 + 143827 = 144008
211 + 143797 = 144008
229 + 143779 = 144008
331 + 143677 = 144008

Showing the first eight; more decompositions exist.
