Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468152, here are decompositions:

5 + 31468147 = 31468152
139 + 31468013 = 31468152
151 + 31468001 = 31468152
241 + 31467911 = 31468152
389 + 31467763 = 31468152
431 + 31467721 = 31468152
433 + 31467719 = 31468152
461 + 31467691 = 31468152

Showing the first eight; more decompositions exist.
