Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77480, here are decompositions:
- 3 + 77477 = 77480
- 61 + 77419 = 77480
- 97 + 77383 = 77480
- 103 + 77377 = 77480
- 157 + 77323 = 77480
- 163 + 77317 = 77480
- 211 + 77269 = 77480
- 241 + 77239 = 77480
Showing the first eight; more decompositions exist.
