Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460492, here are decompositions:

61 + 31460431 = 31460492
79 + 31460413 = 31460492
163 + 31460329 = 31460492
199 + 31460293 = 31460492
211 + 31460281 = 31460492
229 + 31460263 = 31460492
439 + 31460053 = 31460492
499 + 31459993 = 31460492

Showing the first eight; more decompositions exist.
