Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27090, here are decompositions:
- 13 + 27077 = 27090
- 17 + 27073 = 27090
- 23 + 27067 = 27090
- 29 + 27061 = 27090
- 31 + 27059 = 27090
- 47 + 27043 = 27090
- 59 + 27031 = 27090
- 73 + 27017 = 27090
Showing the first eight; more decompositions exist.
