Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462804, here are decompositions:

11 + 31462793 = 31462804
47 + 31462757 = 31462804
53 + 31462751 = 31462804
227 + 31462577 = 31462804
251 + 31462553 = 31462804
257 + 31462547 = 31462804
353 + 31462451 = 31462804
431 + 31462373 = 31462804

Showing the first eight; more decompositions exist.
