Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66246, here are decompositions:
- 7 + 66239 = 66246
- 67 + 66179 = 66246
- 73 + 66173 = 66246
- 109 + 66137 = 66246
- 137 + 66109 = 66246
- 139 + 66107 = 66246
- 157 + 66089 = 66246
- 163 + 66083 = 66246
Showing the first eight; more decompositions exist.
