Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66972, here are decompositions:
- 13 + 66959 = 66972
- 23 + 66949 = 66972
- 29 + 66943 = 66972
- 41 + 66931 = 66972
- 53 + 66919 = 66972
- 83 + 66889 = 66972
- 89 + 66883 = 66972
- 109 + 66863 = 66972
Showing the first eight; more decompositions exist.
