Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477528, here are decompositions:

101 + 31477427 = 31477528
149 + 31477379 = 31477528
179 + 31477349 = 31477528
227 + 31477301 = 31477528
239 + 31477289 = 31477528
347 + 31477181 = 31477528
449 + 31477079 = 31477528
461 + 31477067 = 31477528

Showing the first eight; more decompositions exist.
