Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12416, here are decompositions:
- 3 + 12413 = 12416
- 7 + 12409 = 12416
- 37 + 12379 = 12416
- 43 + 12373 = 12416
- 73 + 12343 = 12416
- 127 + 12289 = 12416
- 139 + 12277 = 12416
- 163 + 12253 = 12416
Showing the first eight; more decompositions exist.
