Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472044, here are decompositions:
- 3 + 31472041 = 31472044
- 41 + 31472003 = 31472044
- 53 + 31471991 = 31472044
- 137 + 31471907 = 31472044
- 257 + 31471787 = 31472044
- 281 + 31471763 = 31472044
- 347 + 31471697 = 31472044
- 467 + 31471577 = 31472044
Showing the first eight; more decompositions exist.
