Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97820, here are decompositions:

7 + 97813 = 97820
31 + 97789 = 97820
43 + 97777 = 97820
109 + 97711 = 97820
211 + 97609 = 97820
241 + 97579 = 97820
271 + 97549 = 97820
367 + 97453 = 97820

Showing the first eight; more decompositions exist.
