Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474130, here are decompositions:
- 19 + 31474111 = 31474130
- 73 + 31474057 = 31474130
- 97 + 31474033 = 31474130
- 139 + 31473991 = 31474130
- 199 + 31473931 = 31474130
- 223 + 31473907 = 31474130
- 229 + 31473901 = 31474130
- 283 + 31473847 = 31474130
Showing the first eight; more decompositions exist.
