Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617172, here are decompositions:
- 19 + 8617153 = 8617172
- 43 + 8617129 = 8617172
- 181 + 8616991 = 8617172
- 271 + 8616901 = 8617172
- 313 + 8616859 = 8617172
- 409 + 8616763 = 8617172
- 439 + 8616733 = 8617172
- 631 + 8616541 = 8617172
Showing the first eight; more decompositions exist.
