Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974788, here are decompositions:
- 19 + 4294974769 = 4294974788
- 271 + 4294974517 = 4294974788
- 331 + 4294974457 = 4294974788
- 337 + 4294974451 = 4294974788
- 457 + 4294974331 = 4294974788
- 739 + 4294974049 = 4294974788
- 877 + 4294973911 = 4294974788
- 919 + 4294973869 = 4294974788
Showing the first eight; more decompositions exist.
