Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71284, here are decompositions:
- 23 + 71261 = 71284
- 47 + 71237 = 71284
- 113 + 71171 = 71284
- 131 + 71153 = 71284
- 137 + 71147 = 71284
- 293 + 70991 = 71284
- 347 + 70937 = 71284
- 383 + 70901 = 71284
Showing the first eight; more decompositions exist.
