Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524542, here are decompositions:

23 + 524519 = 524542
89 + 524453 = 524542
113 + 524429 = 524542
131 + 524411 = 524542
173 + 524369 = 524542
191 + 524351 = 524542
233 + 524309 = 524542
281 + 524261 = 524542

Showing the first eight; more decompositions exist.
