Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28242, here are decompositions:
- 13 + 28229 = 28242
- 23 + 28219 = 28242
- 31 + 28211 = 28242
- 41 + 28201 = 28242
- 59 + 28183 = 28242
- 61 + 28181 = 28242
- 79 + 28163 = 28242
- 131 + 28111 = 28242
Showing the first eight; more decompositions exist.
