Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77620, here are decompositions:
- 3 + 77617 = 77620
- 29 + 77591 = 77620
- 47 + 77573 = 77620
- 71 + 77549 = 77620
- 107 + 77513 = 77620
- 131 + 77489 = 77620
- 149 + 77471 = 77620
- 173 + 77447 = 77620
Showing the first eight; more decompositions exist.
