Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739172, here are decompositions:
- 3 + 8739169 = 8739172
- 5 + 8739167 = 8739172
- 53 + 8739119 = 8739172
- 59 + 8739113 = 8739172
- 149 + 8739023 = 8739172
- 359 + 8738813 = 8739172
- 389 + 8738783 = 8739172
- 443 + 8738729 = 8739172
Showing the first eight; more decompositions exist.
