Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499492, here are decompositions:

61 + 31499431 = 31499492
109 + 31499383 = 31499492
151 + 31499341 = 31499492
163 + 31499329 = 31499492
181 + 31499311 = 31499492
331 + 31499161 = 31499492
499 + 31498993 = 31499492
613 + 31498879 = 31499492

Showing the first eight; more decompositions exist.
