Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742006, here are decompositions:
- 17 + 8741989 = 8742006
- 19 + 8741987 = 8742006
- 23 + 8741983 = 8742006
- 29 + 8741977 = 8742006
- 59 + 8741947 = 8742006
- 73 + 8741933 = 8742006
- 83 + 8741923 = 8742006
- 139 + 8741867 = 8742006
Showing the first eight; more decompositions exist.
