Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742492, here are decompositions:
- 23 + 8742469 = 8742492
- 29 + 8742463 = 8742492
- 43 + 8742449 = 8742492
- 71 + 8742421 = 8742492
- 113 + 8742379 = 8742492
- 139 + 8742353 = 8742492
- 179 + 8742313 = 8742492
- 229 + 8742263 = 8742492
Showing the first eight; more decompositions exist.
