Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726872, here are decompositions:
- 23 + 8726849 = 8726872
- 71 + 8726801 = 8726872
- 83 + 8726789 = 8726872
- 113 + 8726759 = 8726872
- 149 + 8726723 = 8726872
- 173 + 8726699 = 8726872
- 239 + 8726633 = 8726872
- 491 + 8726381 = 8726872
Showing the first eight; more decompositions exist.
