Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461546, here are decompositions:

13 + 31461533 = 31461546
23 + 31461523 = 31461546
29 + 31461517 = 31461546
59 + 31461487 = 31461546
89 + 31461457 = 31461546
197 + 31461349 = 31461546
293 + 31461253 = 31461546
317 + 31461229 = 31461546

Showing the first eight; more decompositions exist.
