Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8038, here are decompositions:
- 29 + 8009 = 8038
- 89 + 7949 = 8038
- 101 + 7937 = 8038
- 131 + 7907 = 8038
- 137 + 7901 = 8038
- 197 + 7841 = 8038
- 281 + 7757 = 8038
- 311 + 7727 = 8038
Showing the first eight; more decompositions exist.
