Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972172, here are decompositions:
- 79 + 4294972093 = 4294972172
- 103 + 4294972069 = 4294972172
- 109 + 4294972063 = 4294972172
- 181 + 4294971991 = 4294972172
- 229 + 4294971943 = 4294972172
- 241 + 4294971931 = 4294972172
- 313 + 4294971859 = 4294972172
- 331 + 4294971841 = 4294972172
Showing the first eight; more decompositions exist.
