Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425148, here are decompositions:
- 199 + 2147424949 = 2147425148
- 331 + 2147424817 = 2147425148
- 439 + 2147424709 = 2147425148
- 571 + 2147424577 = 2147425148
- 1021 + 2147424127 = 2147425148
- 1069 + 2147424079 = 2147425148
- 1231 + 2147423917 = 2147425148
- 1297 + 2147423851 = 2147425148
Showing the first eight; more decompositions exist.
