Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552136, here are decompositions:
- 67 + 31552069 = 31552136
- 79 + 31552057 = 31552136
- 103 + 31552033 = 31552136
- 139 + 31551997 = 31552136
- 157 + 31551979 = 31552136
- 199 + 31551937 = 31552136
- 277 + 31551859 = 31552136
- 283 + 31551853 = 31552136
Showing the first eight; more decompositions exist.
