Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487578, here are decompositions:

17 + 33487561 = 33487578
41 + 33487537 = 33487578
67 + 33487511 = 33487578
71 + 33487507 = 33487578
101 + 33487477 = 33487578
127 + 33487451 = 33487578
191 + 33487387 = 33487578
269 + 33487309 = 33487578

Showing the first eight; more decompositions exist.
