Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73890, here are decompositions:
- 7 + 73883 = 73890
- 13 + 73877 = 73890
- 23 + 73867 = 73890
- 31 + 73859 = 73890
- 41 + 73849 = 73890
- 43 + 73847 = 73890
- 67 + 73823 = 73890
- 71 + 73819 = 73890
Showing the first eight; more decompositions exist.
