Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487972, here are decompositions:

3 + 33487969 = 33487972
59 + 33487913 = 33487972
71 + 33487901 = 33487972
113 + 33487859 = 33487972
239 + 33487733 = 33487972
461 + 33487511 = 33487972
521 + 33487451 = 33487972
653 + 33487319 = 33487972

Showing the first eight; more decompositions exist.
