Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102862, here are decompositions:
- 3 + 102859 = 102862
- 101 + 102761 = 102862
- 251 + 102611 = 102862
- 269 + 102593 = 102862
- 311 + 102551 = 102862
- 359 + 102503 = 102862
- 401 + 102461 = 102862
- 503 + 102359 = 102862
Showing the first eight; more decompositions exist.
