Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87902, here are decompositions:
- 109 + 87793 = 87902
- 151 + 87751 = 87902
- 163 + 87739 = 87902
- 181 + 87721 = 87902
- 211 + 87691 = 87902
- 223 + 87679 = 87902
- 271 + 87631 = 87902
- 313 + 87589 = 87902
Showing the first eight; more decompositions exist.
