Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671490, here are decompositions:
- 19 + 8671471 = 8671490
- 43 + 8671447 = 8671490
- 97 + 8671393 = 8671490
- 109 + 8671381 = 8671490
- 127 + 8671363 = 8671490
- 151 + 8671339 = 8671490
- 199 + 8671291 = 8671490
- 241 + 8671249 = 8671490
Showing the first eight; more decompositions exist.
