Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749242, here are decompositions:
- 13 + 8749229 = 8749242
- 23 + 8749219 = 8749242
- 43 + 8749199 = 8749242
- 79 + 8749163 = 8749242
- 101 + 8749141 = 8749242
- 109 + 8749133 = 8749242
- 193 + 8749049 = 8749242
- 223 + 8749019 = 8749242
Showing the first eight; more decompositions exist.
