Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294970578, here are decompositions:
- 11 + 4294970567 = 4294970578
- 47 + 4294970531 = 4294970578
- 317 + 4294970261 = 4294970578
- 347 + 4294970231 = 4294970578
- 389 + 4294970189 = 4294970578
- 491 + 4294970087 = 4294970578
- 599 + 4294969979 = 4294970578
- 677 + 4294969901 = 4294970578
Showing the first eight; more decompositions exist.
