Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523100, here are decompositions:
- 19 + 31523081 = 31523100
- 47 + 31523053 = 31523100
- 73 + 31523027 = 31523100
- 79 + 31523021 = 31523100
- 97 + 31523003 = 31523100
- 113 + 31522987 = 31523100
- 139 + 31522961 = 31523100
- 149 + 31522951 = 31523100
Showing the first eight; more decompositions exist.
