Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749472, here are decompositions:
- 3 + 8749469 = 8749472
- 163 + 8749309 = 8749472
- 229 + 8749243 = 8749472
- 331 + 8749141 = 8749472
- 499 + 8748973 = 8749472
- 619 + 8748853 = 8749472
- 631 + 8748841 = 8749472
- 661 + 8748811 = 8749472
Showing the first eight; more decompositions exist.
