Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477060, here are decompositions:

3 + 31477057 = 31477060
101 + 31476959 = 31477060
113 + 31476947 = 31477060
179 + 31476881 = 31477060
239 + 31476821 = 31477060
317 + 31476743 = 31477060
449 + 31476611 = 31477060
467 + 31476593 = 31477060

Showing the first eight; more decompositions exist.
