Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449654, here are decompositions:

7 + 31449647 = 31449654
17 + 31449637 = 31449654
43 + 31449611 = 31449654
73 + 31449581 = 31449654
83 + 31449571 = 31449654
97 + 31449557 = 31449654
101 + 31449553 = 31449654
127 + 31449527 = 31449654

Showing the first eight; more decompositions exist.
