Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474020, here are decompositions:

13 + 31474007 = 31474020
29 + 31473991 = 31474020
43 + 31473977 = 31474020
89 + 31473931 = 31474020
103 + 31473917 = 31474020
113 + 31473907 = 31474020
157 + 31473863 = 31474020
173 + 31473847 = 31474020

Showing the first eight; more decompositions exist.
