Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474250, here are decompositions:
- 37 + 31474213 = 31474250
- 79 + 31474171 = 31474250
- 109 + 31474141 = 31474250
- 139 + 31474111 = 31474250
- 193 + 31474057 = 31474250
- 349 + 31473901 = 31474250
- 439 + 31473811 = 31474250
- 547 + 31473703 = 31474250
Showing the first eight; more decompositions exist.
