Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523902, here are decompositions:

73 + 523829 = 523902
101 + 523801 = 523902
109 + 523793 = 523902
131 + 523771 = 523902
139 + 523763 = 523902
173 + 523729 = 523902
229 + 523673 = 523902
233 + 523669 = 523902

Showing the first eight; more decompositions exist.
