Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143800, here are decompositions:

3 + 143797 = 143800
71 + 143729 = 143800
89 + 143711 = 143800
101 + 143699 = 143800
113 + 143687 = 143800
131 + 143669 = 143800
149 + 143651 = 143800
191 + 143609 = 143800

Showing the first eight; more decompositions exist.
