Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88220, here are decompositions:
- 43 + 88177 = 88220
- 103 + 88117 = 88220
- 127 + 88093 = 88220
- 151 + 88069 = 88220
- 229 + 87991 = 88220
- 277 + 87943 = 88220
- 367 + 87853 = 88220
- 409 + 87811 = 88220
Showing the first eight; more decompositions exist.
