Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561138, here are decompositions:

59 + 33561079 = 33561138
71 + 33561067 = 33561138
131 + 33561007 = 33561138
139 + 33560999 = 33561138
199 + 33560939 = 33561138
257 + 33560881 = 33561138
269 + 33560869 = 33561138
311 + 33560827 = 33561138

Showing the first eight; more decompositions exist.
