Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98780, here are decompositions:

7 + 98773 = 98780
43 + 98737 = 98780
67 + 98713 = 98780
139 + 98641 = 98780
307 + 98473 = 98780
313 + 98467 = 98780
337 + 98443 = 98780
373 + 98407 = 98780

Showing the first eight; more decompositions exist.
