Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28550, here are decompositions:
- 3 + 28547 = 28550
- 13 + 28537 = 28550
- 37 + 28513 = 28550
- 73 + 28477 = 28550
- 103 + 28447 = 28550
- 139 + 28411 = 28550
- 157 + 28393 = 28550
- 163 + 28387 = 28550
Showing the first eight; more decompositions exist.
