Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12946, here are decompositions:
- 5 + 12941 = 12946
- 23 + 12923 = 12946
- 29 + 12917 = 12946
- 47 + 12899 = 12946
- 53 + 12893 = 12946
- 137 + 12809 = 12946
- 233 + 12713 = 12946
- 257 + 12689 = 12946
Showing the first eight; more decompositions exist.
