Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11138, here are decompositions:
- 7 + 11131 = 11138
- 19 + 11119 = 11138
- 67 + 11071 = 11138
- 79 + 11059 = 11138
- 151 + 10987 = 11138
- 181 + 10957 = 11138
- 199 + 10939 = 11138
- 229 + 10909 = 11138
Showing the first eight; more decompositions exist.
