Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615164, here are decompositions:
- 11 + 31615153 = 31615164
- 37 + 31615127 = 31615164
- 67 + 31615097 = 31615164
- 101 + 31615063 = 31615164
- 103 + 31615061 = 31615164
- 151 + 31615013 = 31615164
- 157 + 31615007 = 31615164
- 211 + 31614953 = 31615164
Showing the first eight; more decompositions exist.
