Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69980, here are decompositions:

103 + 69877 = 69980
151 + 69829 = 69980
241 + 69739 = 69980
271 + 69709 = 69980
283 + 69697 = 69980
487 + 69493 = 69980
499 + 69481 = 69980
523 + 69457 = 69980

Showing the first eight; more decompositions exist.
