Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425210, here are decompositions:
- 23 + 2147425187 = 2147425210
- 41 + 2147425169 = 2147425210
- 71 + 2147425139 = 2147425210
- 83 + 2147425127 = 2147425210
- 89 + 2147425121 = 2147425210
- 107 + 2147425103 = 2147425210
- 137 + 2147425073 = 2147425210
- 311 + 2147424899 = 2147425210
Showing the first eight; more decompositions exist.
