Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749664, here are decompositions:
- 13 + 8749651 = 8749664
- 37 + 8749627 = 8749664
- 61 + 8749603 = 8749664
- 241 + 8749423 = 8749664
- 307 + 8749357 = 8749664
- 421 + 8749243 = 8749664
- 457 + 8749207 = 8749664
- 523 + 8749141 = 8749664
Showing the first eight; more decompositions exist.
