Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456094, here are decompositions:

73 + 31456021 = 31456094
193 + 31455901 = 31456094
367 + 31455727 = 31456094
457 + 31455637 = 31456094
463 + 31455631 = 31456094
661 + 31455433 = 31456094
727 + 31455367 = 31456094
823 + 31455271 = 31456094

Showing the first eight; more decompositions exist.
