Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87884, here are decompositions:
- 3 + 87881 = 87884
- 7 + 87877 = 87884
- 31 + 87853 = 87884
- 73 + 87811 = 87884
- 163 + 87721 = 87884
- 193 + 87691 = 87884
- 241 + 87643 = 87884
- 271 + 87613 = 87884
Showing the first eight; more decompositions exist.
