Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731944, here are decompositions:
- 5 + 8731939 = 8731944
- 7 + 8731937 = 8731944
- 31 + 8731913 = 8731944
- 37 + 8731907 = 8731944
- 43 + 8731901 = 8731944
- 71 + 8731873 = 8731944
- 83 + 8731861 = 8731944
- 113 + 8731831 = 8731944
Showing the first eight; more decompositions exist.
