Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28524, here are decompositions:
- 7 + 28517 = 28524
- 11 + 28513 = 28524
- 31 + 28493 = 28524
- 47 + 28477 = 28524
- 61 + 28463 = 28524
- 113 + 28411 = 28524
- 131 + 28393 = 28524
- 137 + 28387 = 28524
Showing the first eight; more decompositions exist.
