Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128246, here are decompositions:
- 7 + 128239 = 128246
- 43 + 128203 = 128246
- 73 + 128173 = 128246
- 127 + 128119 = 128246
- 193 + 128053 = 128246
- 199 + 128047 = 128246
- 373 + 127873 = 128246
- 379 + 127867 = 128246
Showing the first eight; more decompositions exist.
