Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498142, here are decompositions:
- 19 + 31498123 = 31498142
- 31 + 31498111 = 31498142
- 73 + 31498069 = 31498142
- 103 + 31498039 = 31498142
- 139 + 31498003 = 31498142
- 163 + 31497979 = 31498142
- 211 + 31497931 = 31498142
- 271 + 31497871 = 31498142
Showing the first eight; more decompositions exist.
