Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27072, here are decompositions:
- 5 + 27067 = 27072
- 11 + 27061 = 27072
- 13 + 27059 = 27072
- 29 + 27043 = 27072
- 41 + 27031 = 27072
- 61 + 27011 = 27072
- 79 + 26993 = 27072
- 113 + 26959 = 27072
Showing the first eight; more decompositions exist.
