Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458546, here are decompositions:

5 + 31458541 = 31458546
19 + 31458527 = 31458546
59 + 31458487 = 31458546
109 + 31458437 = 31458546
127 + 31458419 = 31458546
167 + 31458379 = 31458546
173 + 31458373 = 31458546
269 + 31458277 = 31458546

Showing the first eight; more decompositions exist.
