Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87404, here are decompositions:
- 67 + 87337 = 87404
- 127 + 87277 = 87404
- 151 + 87253 = 87404
- 181 + 87223 = 87404
- 193 + 87211 = 87404
- 223 + 87181 = 87404
- 271 + 87133 = 87404
- 283 + 87121 = 87404
Showing the first eight; more decompositions exist.
