Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743680, here are decompositions:
- 7 + 8743673 = 8743680
- 41 + 8743639 = 8743680
- 47 + 8743633 = 8743680
- 59 + 8743621 = 8743680
- 83 + 8743597 = 8743680
- 97 + 8743583 = 8743680
- 109 + 8743571 = 8743680
- 131 + 8743549 = 8743680
Showing the first eight; more decompositions exist.
