Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28430, here are decompositions:
- 19 + 28411 = 28430
- 37 + 28393 = 28430
- 43 + 28387 = 28430
- 79 + 28351 = 28430
- 151 + 28279 = 28430
- 211 + 28219 = 28430
- 229 + 28201 = 28430
- 307 + 28123 = 28430
Showing the first eight; more decompositions exist.
