Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36978, here are decompositions:
- 5 + 36973 = 36978
- 31 + 36947 = 36978
- 47 + 36931 = 36978
- 59 + 36919 = 36978
- 79 + 36899 = 36978
- 101 + 36877 = 36978
- 107 + 36871 = 36978
- 131 + 36847 = 36978
Showing the first eight; more decompositions exist.
