Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473292, here are decompositions:

29 + 31473263 = 31473292
41 + 31473251 = 31473292
83 + 31473209 = 31473292
89 + 31473203 = 31473292
101 + 31473191 = 31473292
131 + 31473161 = 31473292
251 + 31473041 = 31473292
401 + 31472891 = 31473292

Showing the first eight; more decompositions exist.
