Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80078, here are decompositions:
- 7 + 80071 = 80078
- 79 + 79999 = 80078
- 139 + 79939 = 80078
- 211 + 79867 = 80078
- 277 + 79801 = 80078
- 379 + 79699 = 80078
- 409 + 79669 = 80078
- 421 + 79657 = 80078
Showing the first eight; more decompositions exist.
