Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476142, here are decompositions:

23 + 31476119 = 31476142
29 + 31476113 = 31476142
83 + 31476059 = 31476142
179 + 31475963 = 31476142
233 + 31475909 = 31476142
293 + 31475849 = 31476142
461 + 31475681 = 31476142
563 + 31475579 = 31476142

Showing the first eight; more decompositions exist.
