Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975172, here are decompositions:
- 79 + 4294975093 = 4294975172
- 181 + 4294974991 = 4294975172
- 199 + 4294974973 = 4294975172
- 379 + 4294974793 = 4294975172
- 811 + 4294974361 = 4294975172
- 1033 + 4294974139 = 4294975172
- 1039 + 4294974133 = 4294975172
- 1123 + 4294974049 = 4294975172
Showing the first eight; more decompositions exist.
