Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678472, here are decompositions:
- 73 + 8678399 = 8678472
- 79 + 8678393 = 8678472
- 109 + 8678363 = 8678472
- 113 + 8678359 = 8678472
- 139 + 8678333 = 8678472
- 149 + 8678323 = 8678472
- 269 + 8678203 = 8678472
- 293 + 8678179 = 8678472
Showing the first eight; more decompositions exist.
