Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103972, here are decompositions:
- 3 + 103969 = 103972
- 5 + 103967 = 103972
- 53 + 103919 = 103972
- 59 + 103913 = 103972
- 83 + 103889 = 103972
- 131 + 103841 = 103972
- 269 + 103703 = 103972
- 353 + 103619 = 103972
Showing the first eight; more decompositions exist.
