Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462988, here are decompositions:

19 + 31462969 = 31462988
79 + 31462909 = 31462988
157 + 31462831 = 31462988
181 + 31462807 = 31462988
229 + 31462759 = 31462988
241 + 31462747 = 31462988
379 + 31462609 = 31462988
397 + 31462591 = 31462988

Showing the first eight; more decompositions exist.
