Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465136, here are decompositions:
- 7 + 31465129 = 31465136
- 13 + 31465123 = 31465136
- 37 + 31465099 = 31465136
- 67 + 31465069 = 31465136
- 97 + 31465039 = 31465136
- 103 + 31465033 = 31465136
- 163 + 31464973 = 31465136
- 349 + 31464787 = 31465136
Showing the first eight; more decompositions exist.
