Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88642, here are decompositions:
- 53 + 88589 = 88642
- 149 + 88493 = 88642
- 173 + 88469 = 88642
- 179 + 88463 = 88642
- 263 + 88379 = 88642
- 353 + 88289 = 88642
- 383 + 88259 = 88642
- 401 + 88241 = 88642
Showing the first eight; more decompositions exist.
