Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47228, here are decompositions:
- 7 + 47221 = 47228
- 67 + 47161 = 47228
- 79 + 47149 = 47228
- 109 + 47119 = 47228
- 211 + 47017 = 47228
- 271 + 46957 = 47228
- 367 + 46861 = 47228
- 397 + 46831 = 47228
Showing the first eight; more decompositions exist.
