Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4078, here are decompositions:
- 5 + 4073 = 4078
- 29 + 4049 = 4078
- 59 + 4019 = 4078
- 71 + 4007 = 4078
- 89 + 3989 = 4078
- 131 + 3947 = 4078
- 149 + 3929 = 4078
- 167 + 3911 = 4078
Showing the first eight; more decompositions exist.
