Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972748, here are decompositions:
- 139 + 4294972609 = 4294972748
- 181 + 4294972567 = 4294972748
- 307 + 4294972441 = 4294972748
- 337 + 4294972411 = 4294972748
- 397 + 4294972351 = 4294972748
- 457 + 4294972291 = 4294972748
- 541 + 4294972207 = 4294972748
- 601 + 4294972147 = 4294972748
Showing the first eight; more decompositions exist.
