Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4778, here are decompositions:
- 19 + 4759 = 4778
- 127 + 4651 = 4778
- 139 + 4639 = 4778
- 157 + 4621 = 4778
- 181 + 4597 = 4778
- 211 + 4567 = 4778
- 229 + 4549 = 4778
- 271 + 4507 = 4778
Showing the first eight; more decompositions exist.
