Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711472, here are decompositions:
- 5 + 8711467 = 8711472
- 71 + 8711401 = 8711472
- 73 + 8711399 = 8711472
- 89 + 8711383 = 8711472
- 109 + 8711363 = 8711472
- 113 + 8711359 = 8711472
- 139 + 8711333 = 8711472
- 283 + 8711189 = 8711472
Showing the first eight; more decompositions exist.
