Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461484, here are decompositions:

3 + 31461481 = 31461484
71 + 31461413 = 31461484
191 + 31461293 = 31461484
293 + 31461191 = 31461484
311 + 31461173 = 31461484
557 + 31460927 = 31461484
647 + 31460837 = 31461484
653 + 31460831 = 31461484

Showing the first eight; more decompositions exist.
