Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042388, here are decompositions:

7 + 1042381 = 1042388
19 + 1042369 = 1042388
31 + 1042357 = 1042388
79 + 1042309 = 1042388
307 + 1042081 = 1042388
349 + 1042039 = 1042388
367 + 1042021 = 1042388
397 + 1041991 = 1042388

Showing the first eight; more decompositions exist.
