Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97720, here are decompositions:

47 + 97673 = 97720
71 + 97649 = 97720
107 + 97613 = 97720
113 + 97607 = 97720
137 + 97583 = 97720
149 + 97571 = 97720
167 + 97553 = 97720
173 + 97547 = 97720

Showing the first eight; more decompositions exist.
