Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487542, here are decompositions:

5 + 33487537 = 33487542
29 + 33487513 = 33487542
31 + 33487511 = 33487542
149 + 33487393 = 33487542
199 + 33487343 = 33487542
223 + 33487319 = 33487542
229 + 33487313 = 33487542
233 + 33487309 = 33487542

Showing the first eight; more decompositions exist.
