Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742370, here are decompositions:
- 3 + 8742367 = 8742370
- 11 + 8742359 = 8742370
- 17 + 8742353 = 8742370
- 23 + 8742347 = 8742370
- 53 + 8742317 = 8742370
- 107 + 8742263 = 8742370
- 173 + 8742197 = 8742370
- 293 + 8742077 = 8742370
Showing the first eight; more decompositions exist.
