Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61620, here are decompositions:
- 7 + 61613 = 61620
- 11 + 61609 = 61620
- 17 + 61603 = 61620
- 37 + 61583 = 61620
- 59 + 61561 = 61620
- 61 + 61559 = 61620
- 67 + 61553 = 61620
- 73 + 61547 = 61620
Showing the first eight; more decompositions exist.
