Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483320, here are decompositions:
- 7 + 31483313 = 31483320
- 13 + 31483307 = 31483320
- 59 + 31483261 = 31483320
- 83 + 31483237 = 31483320
- 103 + 31483217 = 31483320
- 107 + 31483213 = 31483320
- 151 + 31483169 = 31483320
- 157 + 31483163 = 31483320
Showing the first eight; more decompositions exist.
