Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972142, here are decompositions:
- 73 + 4294972069 = 4294972142
- 79 + 4294972063 = 4294972142
- 103 + 4294972039 = 4294972142
- 151 + 4294971991 = 4294972142
- 199 + 4294971943 = 4294972142
- 211 + 4294971931 = 4294972142
- 283 + 4294971859 = 4294972142
- 313 + 4294971829 = 4294972142
Showing the first eight; more decompositions exist.
