Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10242, here are decompositions:
- 19 + 10223 = 10242
- 31 + 10211 = 10242
- 61 + 10181 = 10242
- 73 + 10169 = 10242
- 79 + 10163 = 10242
- 83 + 10159 = 10242
- 101 + 10141 = 10242
- 103 + 10139 = 10242
Showing the first eight; more decompositions exist.
