Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749748, here are decompositions:
- 79 + 8749669 = 8749748
- 97 + 8749651 = 8749748
- 199 + 8749549 = 8749748
- 331 + 8749417 = 8749748
- 439 + 8749309 = 8749748
- 541 + 8749207 = 8749748
- 607 + 8749141 = 8749748
- 661 + 8749087 = 8749748
Showing the first eight; more decompositions exist.
