Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3778, here are decompositions:
- 11 + 3767 = 3778
- 17 + 3761 = 3778
- 59 + 3719 = 3778
- 101 + 3677 = 3778
- 107 + 3671 = 3778
- 197 + 3581 = 3778
- 239 + 3539 = 3778
- 251 + 3527 = 3778
Showing the first eight; more decompositions exist.
