Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723976, here are decompositions:
- 29 + 8723947 = 8723976
- 43 + 8723933 = 8723976
- 47 + 8723929 = 8723976
- 67 + 8723909 = 8723976
- 73 + 8723903 = 8723976
- 83 + 8723893 = 8723976
- 89 + 8723887 = 8723976
- 97 + 8723879 = 8723976
Showing the first eight; more decompositions exist.
