Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747992, here are decompositions:
- 5 + 8747987 = 8747992
- 59 + 8747933 = 8747992
- 89 + 8747903 = 8747992
- 101 + 8747891 = 8747992
- 173 + 8747819 = 8747992
- 233 + 8747759 = 8747992
- 269 + 8747723 = 8747992
- 389 + 8747603 = 8747992
Showing the first eight; more decompositions exist.
