Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742552, here are decompositions:
- 11 + 8742541 = 8742552
- 23 + 8742529 = 8742552
- 41 + 8742511 = 8742552
- 53 + 8742499 = 8742552
- 59 + 8742493 = 8742552
- 83 + 8742469 = 8742552
- 89 + 8742463 = 8742552
- 103 + 8742449 = 8742552
Showing the first eight; more decompositions exist.
