Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447704, here are decompositions:

23 + 31447681 = 31447704
31 + 31447673 = 31447704
37 + 31447667 = 31447704
47 + 31447657 = 31447704
61 + 31447643 = 31447704
73 + 31447631 = 31447704
97 + 31447607 = 31447704
131 + 31447573 = 31447704

Showing the first eight; more decompositions exist.
