Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472890, here are decompositions:

41 + 33472849 = 33472890
67 + 33472823 = 33472890
103 + 33472787 = 33472890
107 + 33472783 = 33472890
131 + 33472759 = 33472890
167 + 33472723 = 33472890
193 + 33472697 = 33472890
197 + 33472693 = 33472890

Showing the first eight; more decompositions exist.
