Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474150, here are decompositions:

89 + 31474061 = 31474150
107 + 31474043 = 31474150
173 + 31473977 = 31474150
179 + 31473971 = 31474150
233 + 31473917 = 31474150
263 + 31473887 = 31474150
311 + 31473839 = 31474150
443 + 31473707 = 31474150

Showing the first eight; more decompositions exist.
