Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456754, here are decompositions:

13 + 31456741 = 31456754
103 + 31456651 = 31456754
157 + 31456597 = 31456754
223 + 31456531 = 31456754
313 + 31456441 = 31456754
463 + 31456291 = 31456754
631 + 31456123 = 31456754
661 + 31456093 = 31456754

Showing the first eight; more decompositions exist.
