Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498122, here are decompositions:
- 11 + 31498111 = 31498122
- 53 + 31498069 = 31498122
- 79 + 31498043 = 31498122
- 83 + 31498039 = 31498122
- 113 + 31498009 = 31498122
- 181 + 31497941 = 31498122
- 191 + 31497931 = 31498122
- 193 + 31497929 = 31498122
Showing the first eight; more decompositions exist.
