Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461610, here are decompositions:

41 + 31461569 = 31461610
53 + 31461557 = 31461610
197 + 31461413 = 31461610
269 + 31461341 = 31461610
317 + 31461293 = 31461610
419 + 31461191 = 31461610
431 + 31461179 = 31461610
449 + 31461161 = 31461610

Showing the first eight; more decompositions exist.
