Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499546, here are decompositions:

79 + 31499467 = 31499546
139 + 31499407 = 31499546
163 + 31499383 = 31499546
223 + 31499323 = 31499546
307 + 31499239 = 31499546
409 + 31499137 = 31499546
439 + 31499107 = 31499546
523 + 31499023 = 31499546

Showing the first eight; more decompositions exist.
