Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422198, here are decompositions:
- 59 + 2147422139 = 2147422198
- 71 + 2147422127 = 2147422198
- 101 + 2147422097 = 2147422198
- 137 + 2147422061 = 2147422198
- 179 + 2147422019 = 2147422198
- 461 + 2147421737 = 2147422198
- 617 + 2147421581 = 2147422198
- 1019 + 2147421179 = 2147422198
Showing the first eight; more decompositions exist.
