Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31030, here are decompositions:
- 11 + 31019 = 31030
- 17 + 31013 = 31030
- 47 + 30983 = 31030
- 53 + 30977 = 31030
- 59 + 30971 = 31030
- 89 + 30941 = 31030
- 137 + 30893 = 31030
- 149 + 30881 = 31030
Showing the first eight; more decompositions exist.
