Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974890, here are decompositions:
- 79 + 4294974811 = 4294974890
- 97 + 4294974793 = 4294974890
- 307 + 4294974583 = 4294974890
- 373 + 4294974517 = 4294974890
- 397 + 4294974493 = 4294974890
- 433 + 4294974457 = 4294974890
- 439 + 4294974451 = 4294974890
- 751 + 4294974139 = 4294974890
Showing the first eight; more decompositions exist.
