Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71800, here are decompositions:

11 + 71789 = 71800
23 + 71777 = 71800
59 + 71741 = 71800
89 + 71711 = 71800
101 + 71699 = 71800
107 + 71693 = 71800
137 + 71663 = 71800
167 + 71633 = 71800

Showing the first eight; more decompositions exist.
