Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31038, here are decompositions:
- 5 + 31033 = 31038
- 19 + 31019 = 31038
- 61 + 30977 = 31038
- 67 + 30971 = 31038
- 89 + 30949 = 31038
- 97 + 30941 = 31038
- 101 + 30937 = 31038
- 107 + 30931 = 31038
Showing the first eight; more decompositions exist.
