Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27278, here are decompositions:
- 7 + 27271 = 27278
- 19 + 27259 = 27278
- 37 + 27241 = 27278
- 67 + 27211 = 27278
- 151 + 27127 = 27278
- 211 + 27067 = 27278
- 331 + 26947 = 27278
- 397 + 26881 = 27278
Showing the first eight; more decompositions exist.
