Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746442, here are decompositions:

43 + 8746399 = 8746442
73 + 8746369 = 8746442
139 + 8746303 = 8746442
181 + 8746261 = 8746442
349 + 8746093 = 8746442
373 + 8746069 = 8746442
379 + 8746063 = 8746442
433 + 8746009 = 8746442

Showing the first eight; more decompositions exist.
