Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561142, here are decompositions:

3 + 33561139 = 33561142
53 + 33561089 = 33561142
89 + 33561053 = 33561142
191 + 33560951 = 33561142
401 + 33560741 = 33561142
431 + 33560711 = 33561142
491 + 33560651 = 33561142
509 + 33560633 = 33561142

Showing the first eight; more decompositions exist.
