Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13912, here are decompositions:
- 5 + 13907 = 13912
- 11 + 13901 = 13912
- 29 + 13883 = 13912
- 53 + 13859 = 13912
- 71 + 13841 = 13912
- 83 + 13829 = 13912
- 113 + 13799 = 13912
- 131 + 13781 = 13912
Showing the first eight; more decompositions exist.
