Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703420, here are decompositions:
- 17 + 8703403 = 8703420
- 31 + 8703389 = 8703420
- 41 + 8703379 = 8703420
- 43 + 8703377 = 8703420
- 67 + 8703353 = 8703420
- 73 + 8703347 = 8703420
- 113 + 8703307 = 8703420
- 127 + 8703293 = 8703420
Showing the first eight; more decompositions exist.
