Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72612, here are decompositions:
- 53 + 72559 = 72612
- 61 + 72551 = 72612
- 79 + 72533 = 72612
- 109 + 72503 = 72612
- 131 + 72481 = 72612
- 151 + 72461 = 72612
- 181 + 72431 = 72612
- 191 + 72421 = 72612
Showing the first eight; more decompositions exist.
