Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190788, here are decompositions:

5 + 190783 = 190788
19 + 190769 = 190788
29 + 190759 = 190788
71 + 190717 = 190788
79 + 190709 = 190788
89 + 190699 = 190788
131 + 190657 = 190788
139 + 190649 = 190788

Showing the first eight; more decompositions exist.
