Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66956, here are decompositions:
- 7 + 66949 = 66956
- 13 + 66943 = 66956
- 37 + 66919 = 66956
- 67 + 66889 = 66956
- 73 + 66883 = 66956
- 79 + 66877 = 66956
- 103 + 66853 = 66956
- 193 + 66763 = 66956
Showing the first eight; more decompositions exist.
