Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703990, here are decompositions:
- 19 + 8703971 = 8703990
- 47 + 8703943 = 8703990
- 79 + 8703911 = 8703990
- 101 + 8703889 = 8703990
- 131 + 8703859 = 8703990
- 137 + 8703853 = 8703990
- 149 + 8703841 = 8703990
- 157 + 8703833 = 8703990
Showing the first eight; more decompositions exist.
