Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88128, here are decompositions:
- 11 + 88117 = 88128
- 59 + 88069 = 88128
- 109 + 88019 = 88128
- 127 + 88001 = 88128
- 137 + 87991 = 88128
- 151 + 87977 = 88128
- 167 + 87961 = 88128
- 197 + 87931 = 88128
Showing the first eight; more decompositions exist.
