Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33603972, here are decompositions:

23 + 33603949 = 33603972
43 + 33603929 = 33603972
71 + 33603901 = 33603972
79 + 33603893 = 33603972
113 + 33603859 = 33603972
139 + 33603833 = 33603972
229 + 33603743 = 33603972
373 + 33603599 = 33603972

Showing the first eight; more decompositions exist.
