Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72678, here are decompositions:
- 5 + 72673 = 72678
- 7 + 72671 = 72678
- 17 + 72661 = 72678
- 29 + 72649 = 72678
- 31 + 72647 = 72678
- 61 + 72617 = 72678
- 101 + 72577 = 72678
- 127 + 72551 = 72678
Showing the first eight; more decompositions exist.
