Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72004, here are decompositions:
- 5 + 71999 = 72004
- 11 + 71993 = 72004
- 17 + 71987 = 72004
- 41 + 71963 = 72004
- 71 + 71933 = 72004
- 137 + 71867 = 72004
- 167 + 71837 = 72004
- 197 + 71807 = 72004
Showing the first eight; more decompositions exist.
