Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28418, here are decompositions:
- 7 + 28411 = 28418
- 31 + 28387 = 28418
- 67 + 28351 = 28418
- 109 + 28309 = 28418
- 139 + 28279 = 28418
- 199 + 28219 = 28418
- 307 + 28111 = 28418
- 331 + 28087 = 28418
Showing the first eight; more decompositions exist.
