Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425144, here are decompositions:
- 5 + 2147425139 = 2147425144
- 17 + 2147425127 = 2147425144
- 23 + 2147425121 = 2147425144
- 41 + 2147425103 = 2147425144
- 71 + 2147425073 = 2147425144
- 251 + 2147424893 = 2147425144
- 281 + 2147424863 = 2147425144
- 317 + 2147424827 = 2147425144
Showing the first eight; more decompositions exist.
