Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88130, here are decompositions:
- 13 + 88117 = 88130
- 37 + 88093 = 88130
- 61 + 88069 = 88130
- 127 + 88003 = 88130
- 139 + 87991 = 88130
- 157 + 87973 = 88130
- 199 + 87931 = 88130
- 277 + 87853 = 88130
Showing the first eight; more decompositions exist.
