Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972100, here are decompositions:
- 7 + 4294972093 = 4294972100
- 31 + 4294972069 = 4294972100
- 37 + 4294972063 = 4294972100
- 61 + 4294972039 = 4294972100
- 109 + 4294971991 = 4294972100
- 157 + 4294971943 = 4294972100
- 163 + 4294971937 = 4294972100
- 241 + 4294971859 = 4294972100
Showing the first eight; more decompositions exist.
