Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72624, here are decompositions:
- 7 + 72617 = 72624
- 11 + 72613 = 72624
- 47 + 72577 = 72624
- 73 + 72551 = 72624
- 127 + 72497 = 72624
- 131 + 72493 = 72624
- 157 + 72467 = 72624
- 163 + 72461 = 72624
Showing the first eight; more decompositions exist.
