Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544148, here are decompositions:
- 17 + 31544131 = 31544148
- 59 + 31544089 = 31544148
- 71 + 31544077 = 31544148
- 107 + 31544041 = 31544148
- 109 + 31544039 = 31544148
- 127 + 31544021 = 31544148
- 137 + 31544011 = 31544148
- 151 + 31543997 = 31544148
Showing the first eight; more decompositions exist.
