Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11812, here are decompositions:
- 5 + 11807 = 11812
- 11 + 11801 = 11812
- 23 + 11789 = 11812
- 29 + 11783 = 11812
- 113 + 11699 = 11812
- 131 + 11681 = 11812
- 179 + 11633 = 11812
- 191 + 11621 = 11812
Showing the first eight; more decompositions exist.
