Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27128, here are decompositions:
- 19 + 27109 = 27128
- 37 + 27091 = 27128
- 61 + 27067 = 27128
- 67 + 27061 = 27128
- 97 + 27031 = 27128
- 181 + 26947 = 27128
- 307 + 26821 = 27128
- 397 + 26731 = 27128
Showing the first eight; more decompositions exist.
