Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147465292, here are decompositions:
- 53 + 2147465239 = 2147465292
- 59 + 2147465233 = 2147465292
- 79 + 2147465213 = 2147465292
- 103 + 2147465189 = 2147465292
- 131 + 2147465161 = 2147465292
- 139 + 2147465153 = 2147465292
- 283 + 2147465009 = 2147465292
- 331 + 2147464961 = 2147465292
Showing the first eight; more decompositions exist.
