Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703240, here are decompositions:
- 59 + 8703181 = 8703240
- 67 + 8703173 = 8703240
- 89 + 8703151 = 8703240
- 101 + 8703139 = 8703240
- 103 + 8703137 = 8703240
- 127 + 8703113 = 8703240
- 149 + 8703091 = 8703240
- 151 + 8703089 = 8703240
Showing the first eight; more decompositions exist.
