Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572478, here are decompositions:

31 + 33572447 = 33572478
61 + 33572417 = 33572478
97 + 33572381 = 33572478
101 + 33572377 = 33572478
127 + 33572351 = 33572478
131 + 33572347 = 33572478
139 + 33572339 = 33572478
167 + 33572311 = 33572478

Showing the first eight; more decompositions exist.
