Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577206, here are decompositions:
- 47 + 31577159 = 31577206
- 149 + 31577057 = 31577206
- 197 + 31577009 = 31577206
- 239 + 31576967 = 31577206
- 257 + 31576949 = 31577206
- 317 + 31576889 = 31577206
- 467 + 31576739 = 31577206
- 503 + 31576703 = 31577206
Showing the first eight; more decompositions exist.
