Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556390, here are decompositions:

29 + 33556361 = 33556390
47 + 33556343 = 33556390
89 + 33556301 = 33556390
233 + 33556157 = 33556390
353 + 33556037 = 33556390
401 + 33555989 = 33556390
419 + 33555971 = 33556390
431 + 33555959 = 33556390

Showing the first eight; more decompositions exist.
