Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456546, here are decompositions:

29 + 31456517 = 31456546
59 + 31456487 = 31456546
167 + 31456379 = 31456546
227 + 31456319 = 31456546
269 + 31456277 = 31456546
347 + 31456199 = 31456546
353 + 31456193 = 31456546
383 + 31456163 = 31456546

Showing the first eight; more decompositions exist.
