Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28502, here are decompositions:
- 3 + 28499 = 28502
- 73 + 28429 = 28502
- 109 + 28393 = 28502
- 151 + 28351 = 28502
- 193 + 28309 = 28502
- 223 + 28279 = 28502
- 283 + 28219 = 28502
- 379 + 28123 = 28502
Showing the first eight; more decompositions exist.
