Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972238, here are decompositions:
- 31 + 4294972207 = 4294972238
- 199 + 4294972039 = 4294972238
- 307 + 4294971931 = 4294972238
- 379 + 4294971859 = 4294972238
- 397 + 4294971841 = 4294972238
- 409 + 4294971829 = 4294972238
- 457 + 4294971781 = 4294972238
- 631 + 4294971607 = 4294972238
Showing the first eight; more decompositions exist.
