Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972618, here are decompositions:
- 5 + 4294972613 = 4294972618
- 59 + 4294972559 = 4294972618
- 137 + 4294972481 = 4294972618
- 197 + 4294972421 = 4294972618
- 281 + 4294972337 = 4294972618
- 311 + 4294972307 = 4294972618
- 467 + 4294972151 = 4294972618
- 509 + 4294972109 = 4294972618
Showing the first eight; more decompositions exist.
