Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482994, here are decompositions:

3 + 31482991 = 31482994
17 + 31482977 = 31482994
47 + 31482947 = 31482994
173 + 31482821 = 31482994
233 + 31482761 = 31482994
251 + 31482743 = 31482994
311 + 31482683 = 31482994
353 + 31482641 = 31482994

Showing the first eight; more decompositions exist.
