Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476178, here are decompositions:

29 + 31476149 = 31476178
59 + 31476119 = 31476178
269 + 31475909 = 31476178
401 + 31475777 = 31476178
509 + 31475669 = 31476178
599 + 31475579 = 31476178
719 + 31475459 = 31476178
857 + 31475321 = 31476178

Showing the first eight; more decompositions exist.
