Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529390, here are decompositions:
- 31 + 31529359 = 31529390
- 37 + 31529353 = 31529390
- 43 + 31529347 = 31529390
- 223 + 31529167 = 31529390
- 241 + 31529149 = 31529390
- 283 + 31529107 = 31529390
- 337 + 31529053 = 31529390
- 397 + 31528993 = 31529390
Showing the first eight; more decompositions exist.
