Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468752, here are decompositions:

53 + 31468699 = 31468752
163 + 31468589 = 31468752
179 + 31468573 = 31468752
181 + 31468571 = 31468752
193 + 31468559 = 31468752
199 + 31468553 = 31468752
223 + 31468529 = 31468752
229 + 31468523 = 31468752

Showing the first eight; more decompositions exist.
