Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11142, here are decompositions:
- 11 + 11131 = 11142
- 23 + 11119 = 11142
- 29 + 11113 = 11142
- 59 + 11083 = 11142
- 71 + 11071 = 11142
- 73 + 11069 = 11142
- 83 + 11059 = 11142
- 139 + 11003 = 11142
Showing the first eight; more decompositions exist.
