Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465142, here are decompositions:
- 13 + 31465129 = 31465142
- 19 + 31465123 = 31465142
- 31 + 31465111 = 31465142
- 43 + 31465099 = 31465142
- 73 + 31465069 = 31465142
- 103 + 31465039 = 31465142
- 109 + 31465033 = 31465142
- 139 + 31465003 = 31465142
Showing the first eight; more decompositions exist.
