Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1088, here are decompositions:
- 19 + 1069 = 1088
- 37 + 1051 = 1088
- 67 + 1021 = 1088
- 79 + 1009 = 1088
- 97 + 991 = 1088
- 151 + 937 = 1088
- 181 + 907 = 1088
- 211 + 877 = 1088
Showing the first eight; more decompositions exist.
