Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517444, here are decompositions:

3 + 31517441 = 31517444
31 + 31517413 = 31517444
37 + 31517407 = 31517444
433 + 31517011 = 31517444
463 + 31516981 = 31517444
691 + 31516753 = 31517444
811 + 31516633 = 31517444
877 + 31516567 = 31517444

Showing the first eight; more decompositions exist.
