Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477132, here are decompositions:

53 + 31477079 = 31477132
173 + 31476959 = 31477132
251 + 31476881 = 31477132
311 + 31476821 = 31477132
389 + 31476743 = 31477132
509 + 31476623 = 31477132
521 + 31476611 = 31477132
683 + 31476449 = 31477132

Showing the first eight; more decompositions exist.
