Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466842, here are decompositions:
- 83 + 31466759 = 31466842
- 89 + 31466753 = 31466842
- 149 + 31466693 = 31466842
- 293 + 31466549 = 31466842
- 461 + 31466381 = 31466842
- 593 + 31466249 = 31466842
- 839 + 31466003 = 31466842
- 863 + 31465979 = 31466842
Showing the first eight; more decompositions exist.
