Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37890, here are decompositions:
- 11 + 37879 = 37890
- 19 + 37871 = 37890
- 29 + 37861 = 37890
- 37 + 37853 = 37890
- 43 + 37847 = 37890
- 59 + 37831 = 37890
- 79 + 37811 = 37890
- 107 + 37783 = 37890
Showing the first eight; more decompositions exist.
