Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102938, here are decompositions:
- 7 + 102931 = 102938
- 61 + 102877 = 102938
- 67 + 102871 = 102938
- 79 + 102859 = 102938
- 97 + 102841 = 102938
- 109 + 102829 = 102938
- 127 + 102811 = 102938
- 271 + 102667 = 102938
Showing the first eight; more decompositions exist.
