Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690136, here are decompositions:
- 17 + 8690119 = 8690136
- 19 + 8690117 = 8690136
- 43 + 8690093 = 8690136
- 47 + 8690089 = 8690136
- 67 + 8690069 = 8690136
- 73 + 8690063 = 8690136
- 139 + 8689997 = 8690136
- 149 + 8689987 = 8690136
Showing the first eight; more decompositions exist.
