Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544142, here are decompositions:
- 11 + 31544131 = 31544142
- 43 + 31544099 = 31544142
- 53 + 31544089 = 31544142
- 89 + 31544053 = 31544142
- 101 + 31544041 = 31544142
- 103 + 31544039 = 31544142
- 109 + 31544033 = 31544142
- 131 + 31544011 = 31544142
Showing the first eight; more decompositions exist.
