Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71228, here are decompositions:
- 19 + 71209 = 71228
- 37 + 71191 = 71228
- 61 + 71167 = 71228
- 67 + 71161 = 71228
- 109 + 71119 = 71228
- 139 + 71089 = 71228
- 229 + 70999 = 71228
- 271 + 70957 = 71228
Showing the first eight; more decompositions exist.
