Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742032, here are decompositions:
- 43 + 8741989 = 8742032
- 109 + 8741923 = 8742032
- 193 + 8741839 = 8742032
- 283 + 8741749 = 8742032
- 349 + 8741683 = 8742032
- 499 + 8741533 = 8742032
- 601 + 8741431 = 8742032
- 631 + 8741401 = 8742032
Showing the first eight; more decompositions exist.
