Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724744, here are decompositions:
- 5 + 8724739 = 8724744
- 23 + 8724721 = 8724744
- 31 + 8724713 = 8724744
- 47 + 8724697 = 8724744
- 101 + 8724643 = 8724744
- 103 + 8724641 = 8724744
- 113 + 8724631 = 8724744
- 233 + 8724511 = 8724744
Showing the first eight; more decompositions exist.
