Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994442, here are decompositions:

73 + 994369 = 994442
79 + 994363 = 994442
103 + 994339 = 994442
139 + 994303 = 994442
193 + 994249 = 994442
349 + 994093 = 994442
373 + 994069 = 994442
499 + 993943 = 994442

Showing the first eight; more decompositions exist.
