Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72974, here are decompositions:
- 37 + 72937 = 72974
- 43 + 72931 = 72974
- 67 + 72907 = 72974
- 73 + 72901 = 72974
- 103 + 72871 = 72974
- 151 + 72823 = 72974
- 157 + 72817 = 72974
- 211 + 72763 = 72974
Showing the first eight; more decompositions exist.
