Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015620, here are decompositions:
- 17 + 1015603 = 1015620
- 19 + 1015601 = 1015620
- 59 + 1015561 = 1015620
- 61 + 1015559 = 1015620
- 71 + 1015549 = 1015620
- 79 + 1015541 = 1015620
- 97 + 1015523 = 1015620
- 103 + 1015517 = 1015620
Showing the first eight; more decompositions exist.
