Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741642, here are decompositions:
- 3 + 8741639 = 8741642
- 79 + 8741563 = 8741642
- 109 + 8741533 = 8741642
- 139 + 8741503 = 8741642
- 163 + 8741479 = 8741642
- 211 + 8741431 = 8741642
- 241 + 8741401 = 8741642
- 271 + 8741371 = 8741642
Showing the first eight; more decompositions exist.
