Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648138, here are decompositions:
- 7 + 8648131 = 8648138
- 211 + 8647927 = 8648138
- 241 + 8647897 = 8648138
- 337 + 8647801 = 8648138
- 379 + 8647759 = 8648138
- 439 + 8647699 = 8648138
- 571 + 8647567 = 8648138
- 601 + 8647537 = 8648138
Showing the first eight; more decompositions exist.
