Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28412, here are decompositions:
- 3 + 28409 = 28412
- 19 + 28393 = 28412
- 61 + 28351 = 28412
- 103 + 28309 = 28412
- 193 + 28219 = 28412
- 211 + 28201 = 28412
- 229 + 28183 = 28412
- 313 + 28099 = 28412
Showing the first eight; more decompositions exist.
