Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609544, here are decompositions:
- 3 + 31609541 = 31609544
- 13 + 31609531 = 31609544
- 151 + 31609393 = 31609544
- 163 + 31609381 = 31609544
- 277 + 31609267 = 31609544
- 313 + 31609231 = 31609544
- 331 + 31609213 = 31609544
- 433 + 31609111 = 31609544
Showing the first eight; more decompositions exist.
