Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77328, here are decompositions:
- 5 + 77323 = 77328
- 11 + 77317 = 77328
- 37 + 77291 = 77328
- 59 + 77269 = 77328
- 61 + 77267 = 77328
- 67 + 77261 = 77328
- 79 + 77249 = 77328
- 89 + 77239 = 77328
Showing the first eight; more decompositions exist.
