Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128150, here are decompositions:
- 3 + 128147 = 128150
- 31 + 128119 = 128150
- 37 + 128113 = 128150
- 97 + 128053 = 128150
- 103 + 128047 = 128150
- 199 + 127951 = 128150
- 229 + 127921 = 128150
- 277 + 127873 = 128150
Showing the first eight; more decompositions exist.
