Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83770, here are decompositions:

53 + 83717 = 83770
107 + 83663 = 83770
131 + 83639 = 83770
149 + 83621 = 83770
173 + 83597 = 83770
179 + 83591 = 83770
191 + 83579 = 83770
233 + 83537 = 83770

Showing the first eight; more decompositions exist.
