Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474190, here are decompositions:
- 19 + 31474171 = 31474190
- 61 + 31474129 = 31474190
- 79 + 31474111 = 31474190
- 157 + 31474033 = 31474190
- 199 + 31473991 = 31474190
- 283 + 31473907 = 31474190
- 379 + 31473811 = 31474190
- 409 + 31473781 = 31474190
Showing the first eight; more decompositions exist.
