Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729670, here are decompositions:
- 11 + 8729659 = 8729670
- 23 + 8729647 = 8729670
- 29 + 8729641 = 8729670
- 41 + 8729629 = 8729670
- 67 + 8729603 = 8729670
- 107 + 8729563 = 8729670
- 113 + 8729557 = 8729670
- 127 + 8729543 = 8729670
Showing the first eight; more decompositions exist.
