Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523202, here are decompositions:
- 41 + 31523161 = 31523202
- 59 + 31523143 = 31523202
- 71 + 31523131 = 31523202
- 83 + 31523119 = 31523202
- 89 + 31523113 = 31523202
- 103 + 31523099 = 31523202
- 149 + 31523053 = 31523202
- 181 + 31523021 = 31523202
Showing the first eight; more decompositions exist.
