Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80138, here are decompositions:
- 31 + 80107 = 80138
- 61 + 80077 = 80138
- 67 + 80071 = 80138
- 139 + 79999 = 80138
- 151 + 79987 = 80138
- 199 + 79939 = 80138
- 271 + 79867 = 80138
- 277 + 79861 = 80138
Showing the first eight; more decompositions exist.
