Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626140, here are decompositions:
- 11 + 8626129 = 8626140
- 31 + 8626109 = 8626140
- 37 + 8626103 = 8626140
- 41 + 8626099 = 8626140
- 73 + 8626067 = 8626140
- 79 + 8626061 = 8626140
- 97 + 8626043 = 8626140
- 139 + 8626001 = 8626140
Showing the first eight; more decompositions exist.
