Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477192, here are decompositions:

11 + 31477181 = 31477192
29 + 31477163 = 31477192
113 + 31477079 = 31477192
233 + 31476959 = 31477192
311 + 31476881 = 31477192
449 + 31476743 = 31477192
569 + 31476623 = 31477192
599 + 31476593 = 31477192

Showing the first eight; more decompositions exist.
