Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425972, here are decompositions:
- 101 + 2147425871 = 2147425972
- 431 + 2147425541 = 2147425972
- 971 + 2147425001 = 2147425972
- 1103 + 2147424869 = 2147425972
- 1109 + 2147424863 = 2147425972
- 1163 + 2147424809 = 2147425972
- 1409 + 2147424563 = 2147425972
- 1439 + 2147424533 = 2147425972
Showing the first eight; more decompositions exist.
