Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474030, here are decompositions:

23 + 31474007 = 31474030
53 + 31473977 = 31474030
59 + 31473971 = 31474030
113 + 31473917 = 31474030
167 + 31473863 = 31474030
191 + 31473839 = 31474030
251 + 31473779 = 31474030
431 + 31473599 = 31474030

Showing the first eight; more decompositions exist.
