Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723736, here are decompositions:
- 5 + 8723731 = 8723736
- 29 + 8723707 = 8723736
- 59 + 8723677 = 8723736
- 83 + 8723653 = 8723736
- 97 + 8723639 = 8723736
- 127 + 8723609 = 8723736
- 167 + 8723569 = 8723736
- 239 + 8723497 = 8723736
Showing the first eight; more decompositions exist.
