Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80278, here are decompositions:
- 5 + 80273 = 80278
- 47 + 80231 = 80278
- 71 + 80207 = 80278
- 101 + 80177 = 80278
- 131 + 80147 = 80278
- 137 + 80141 = 80278
- 167 + 80111 = 80278
- 227 + 80051 = 80278
Showing the first eight; more decompositions exist.
