Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129118, here are decompositions:
- 5 + 129113 = 129118
- 29 + 129089 = 129118
- 107 + 129011 = 129118
- 131 + 128987 = 129118
- 137 + 128981 = 129118
- 149 + 128969 = 129118
- 167 + 128951 = 129118
- 179 + 128939 = 129118
Showing the first eight; more decompositions exist.
