Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88140, here are decompositions:
- 11 + 88129 = 88140
- 23 + 88117 = 88140
- 47 + 88093 = 88140
- 61 + 88079 = 88140
- 71 + 88069 = 88140
- 103 + 88037 = 88140
- 137 + 88003 = 88140
- 139 + 88001 = 88140
Showing the first eight; more decompositions exist.
