Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742360, here are decompositions:
- 7 + 8742353 = 8742360
- 13 + 8742347 = 8742360
- 43 + 8742317 = 8742360
- 47 + 8742313 = 8742360
- 97 + 8742263 = 8742360
- 101 + 8742259 = 8742360
- 163 + 8742197 = 8742360
- 167 + 8742193 = 8742360
Showing the first eight; more decompositions exist.
