Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504072, here are decompositions:
- 59 + 31504013 = 31504072
- 101 + 31503971 = 31504072
- 263 + 31503809 = 31504072
- 293 + 31503779 = 31504072
- 359 + 31503713 = 31504072
- 503 + 31503569 = 31504072
- 563 + 31503509 = 31504072
- 863 + 31503209 = 31504072
Showing the first eight; more decompositions exist.
