Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711664, here are decompositions:
- 7 + 8711657 = 8711664
- 11 + 8711653 = 8711664
- 37 + 8711627 = 8711664
- 43 + 8711621 = 8711664
- 47 + 8711617 = 8711664
- 61 + 8711603 = 8711664
- 103 + 8711561 = 8711664
- 113 + 8711551 = 8711664
Showing the first eight; more decompositions exist.
