Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87206, here are decompositions:
- 19 + 87187 = 87206
- 73 + 87133 = 87206
- 103 + 87103 = 87206
- 157 + 87049 = 87206
- 193 + 87013 = 87206
- 277 + 86929 = 87206
- 283 + 86923 = 87206
- 337 + 86869 = 87206
Showing the first eight; more decompositions exist.
