Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045442, here are decompositions:

19 + 1045423 = 1045442
31 + 1045411 = 1045442
313 + 1045129 = 1045442
331 + 1045111 = 1045442
379 + 1045063 = 1045442
421 + 1045021 = 1045442
439 + 1045003 = 1045442
631 + 1044811 = 1045442

Showing the first eight; more decompositions exist.
