Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460888, here are decompositions:

37 + 31460851 = 31460888
79 + 31460809 = 31460888
97 + 31460791 = 31460888
211 + 31460677 = 31460888
241 + 31460647 = 31460888
307 + 31460581 = 31460888
337 + 31460551 = 31460888
379 + 31460509 = 31460888

Showing the first eight; more decompositions exist.
