Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37978, here are decompositions:
- 11 + 37967 = 37978
- 71 + 37907 = 37978
- 89 + 37889 = 37978
- 107 + 37871 = 37978
- 131 + 37847 = 37978
- 167 + 37811 = 37978
- 179 + 37799 = 37978
- 197 + 37781 = 37978
Showing the first eight; more decompositions exist.
