Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938, here are decompositions:
- 19 + 919 = 938
- 31 + 907 = 938
- 61 + 877 = 938
- 79 + 859 = 938
- 109 + 829 = 938
- 127 + 811 = 938
- 151 + 787 = 938
- 181 + 757 = 938
Showing the first eight; more decompositions exist.
