Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28604, here are decompositions:
- 7 + 28597 = 28604
- 13 + 28591 = 28604
- 31 + 28573 = 28604
- 67 + 28537 = 28604
- 127 + 28477 = 28604
- 157 + 28447 = 28604
- 193 + 28411 = 28604
- 211 + 28393 = 28604
Showing the first eight; more decompositions exist.
