Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522378, here are decompositions:

5 + 522373 = 522378
7 + 522371 = 522378
41 + 522337 = 522378
61 + 522317 = 522378
89 + 522289 = 522378
97 + 522281 = 522378
127 + 522251 = 522378
139 + 522239 = 522378

Showing the first eight; more decompositions exist.
