Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542578, here are decompositions:

5 + 33542573 = 33542578
11 + 33542567 = 33542578
89 + 33542489 = 33542578
101 + 33542477 = 33542578
239 + 33542339 = 33542578
257 + 33542321 = 33542578
281 + 33542297 = 33542578
317 + 33542261 = 33542578

Showing the first eight; more decompositions exist.
