Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3126, here are decompositions:
- 5 + 3121 = 3126
- 7 + 3119 = 3126
- 17 + 3109 = 3126
- 37 + 3089 = 3126
- 43 + 3083 = 3126
- 47 + 3079 = 3126
- 59 + 3067 = 3126
- 89 + 3037 = 3126
Showing the first eight; more decompositions exist.
