Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473194, here are decompositions:
- 7 + 2147473187 = 2147473194
- 43 + 2147473151 = 2147473194
- 67 + 2147473127 = 2147473194
- 73 + 2147473121 = 2147473194
- 271 + 2147472923 = 2147473194
- 277 + 2147472917 = 2147473194
- 311 + 2147472883 = 2147473194
- 331 + 2147472863 = 2147473194
Showing the first eight; more decompositions exist.
