Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11412, here are decompositions:
- 13 + 11399 = 11412
- 19 + 11393 = 11412
- 29 + 11383 = 11412
- 43 + 11369 = 11412
- 59 + 11353 = 11412
- 61 + 11351 = 11412
- 83 + 11329 = 11412
- 101 + 11311 = 11412
Showing the first eight; more decompositions exist.
