Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87802, here are decompositions:
- 5 + 87797 = 87802
- 59 + 87743 = 87802
- 83 + 87719 = 87802
- 101 + 87701 = 87802
- 131 + 87671 = 87802
- 173 + 87629 = 87802
- 179 + 87623 = 87802
- 263 + 87539 = 87802
Showing the first eight; more decompositions exist.
