Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144750, here are decompositions:

13 + 144737 = 144750
19 + 144731 = 144750
31 + 144719 = 144750
41 + 144709 = 144750
79 + 144671 = 144750
83 + 144667 = 144750
139 + 144611 = 144750
157 + 144593 = 144750

Showing the first eight; more decompositions exist.
