Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28544, here are decompositions:
- 3 + 28541 = 28544
- 7 + 28537 = 28544
- 31 + 28513 = 28544
- 67 + 28477 = 28544
- 97 + 28447 = 28544
- 151 + 28393 = 28544
- 157 + 28387 = 28544
- 193 + 28351 = 28544
Showing the first eight; more decompositions exist.
