Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452798, here are decompositions:

5 + 31452793 = 31452798
29 + 31452769 = 31452798
59 + 31452739 = 31452798
67 + 31452731 = 31452798
71 + 31452727 = 31452798
79 + 31452719 = 31452798
131 + 31452667 = 31452798
149 + 31452649 = 31452798

Showing the first eight; more decompositions exist.
