Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464002, here are decompositions:

43 + 31463959 = 31464002
61 + 31463941 = 31464002
109 + 31463893 = 31464002
223 + 31463779 = 31464002
313 + 31463689 = 31464002
613 + 31463389 = 31464002
673 + 31463329 = 31464002
733 + 31463269 = 31464002

Showing the first eight; more decompositions exist.
