Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83688, here are decompositions:
- 47 + 83641 = 83688
- 67 + 83621 = 83688
- 71 + 83617 = 83688
- 79 + 83609 = 83688
- 97 + 83591 = 83688
- 109 + 83579 = 83688
- 127 + 83561 = 83688
- 131 + 83557 = 83688
Showing the first eight; more decompositions exist.
