Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749212, here are decompositions:
- 5 + 8749207 = 8749212
- 13 + 8749199 = 8749212
- 61 + 8749151 = 8749212
- 71 + 8749141 = 8749212
- 79 + 8749133 = 8749212
- 163 + 8749049 = 8749212
- 193 + 8749019 = 8749212
- 211 + 8749001 = 8749212
Showing the first eight; more decompositions exist.
