Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972154, here are decompositions:
- 3 + 4294972151 = 4294972154
- 7 + 4294972147 = 4294972154
- 37 + 4294972117 = 4294972154
- 61 + 4294972093 = 4294972154
- 103 + 4294972051 = 4294972154
- 163 + 4294971991 = 4294972154
- 211 + 4294971943 = 4294972154
- 223 + 4294971931 = 4294972154
Showing the first eight; more decompositions exist.
