Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455854, here are decompositions:

13 + 31455841 = 31455854
103 + 31455751 = 31455854
127 + 31455727 = 31455854
151 + 31455703 = 31455854
223 + 31455631 = 31455854
421 + 31455433 = 31455854
457 + 31455397 = 31455854
487 + 31455367 = 31455854

Showing the first eight; more decompositions exist.
