Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72046, here are decompositions:
- 3 + 72043 = 72046
- 47 + 71999 = 72046
- 53 + 71993 = 72046
- 59 + 71987 = 72046
- 83 + 71963 = 72046
- 113 + 71933 = 72046
- 137 + 71909 = 72046
- 167 + 71879 = 72046
Showing the first eight; more decompositions exist.
