Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029138, here are decompositions:
- 29 + 1029109 = 1029138
- 101 + 1029037 = 1029138
- 137 + 1029001 = 1029138
- 139 + 1028999 = 1029138
- 157 + 1028981 = 1029138
- 181 + 1028957 = 1029138
- 197 + 1028941 = 1029138
- 199 + 1028939 = 1029138
Showing the first eight; more decompositions exist.
