Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149038, here are decompositions:
- 5 + 149033 = 149038
- 11 + 149027 = 149038
- 17 + 149021 = 149038
- 41 + 148997 = 149038
- 47 + 148991 = 149038
- 89 + 148949 = 149038
- 107 + 148931 = 149038
- 179 + 148859 = 149038
Showing the first eight; more decompositions exist.
