Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143700, here are decompositions:

13 + 143687 = 143700
23 + 143677 = 143700
31 + 143669 = 143700
47 + 143653 = 143700
71 + 143629 = 143700
83 + 143617 = 143700
107 + 143593 = 143700
127 + 143573 = 143700

Showing the first eight; more decompositions exist.
