Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729448, here are decompositions:
- 19 + 8729429 = 8729448
- 37 + 8729411 = 8729448
- 47 + 8729401 = 8729448
- 59 + 8729389 = 8729448
- 131 + 8729317 = 8729448
- 139 + 8729309 = 8729448
- 157 + 8729291 = 8729448
- 199 + 8729249 = 8729448
Showing the first eight; more decompositions exist.
