Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742394, here are decompositions:

41 + 8742353 = 8742394
47 + 8742347 = 8742394
131 + 8742263 = 8742394
197 + 8742197 = 8742394
233 + 8742161 = 8742394
317 + 8742077 = 8742394
383 + 8742011 = 8742394
443 + 8741951 = 8742394

Showing the first eight; more decompositions exist.
