Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544136, here are decompositions:
- 5 + 31544131 = 31544136
- 37 + 31544099 = 31544136
- 47 + 31544089 = 31544136
- 59 + 31544077 = 31544136
- 79 + 31544057 = 31544136
- 83 + 31544053 = 31544136
- 97 + 31544039 = 31544136
- 103 + 31544033 = 31544136
Showing the first eight; more decompositions exist.
