Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178700, here are decompositions:

3 + 178697 = 178700
7 + 178693 = 178700
19 + 178681 = 178700
61 + 178639 = 178700
73 + 178627 = 178700
79 + 178621 = 178700
97 + 178603 = 178700
103 + 178597 = 178700

Showing the first eight; more decompositions exist.
