Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697744, here are decompositions:
- 37 + 8697707 = 8697744
- 47 + 8697697 = 8697744
- 53 + 8697691 = 8697744
- 61 + 8697683 = 8697744
- 67 + 8697677 = 8697744
- 103 + 8697641 = 8697744
- 131 + 8697613 = 8697744
- 137 + 8697607 = 8697744
Showing the first eight; more decompositions exist.
