Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547774, here are decompositions:

43 + 31547731 = 31547774
67 + 31547707 = 31547774
73 + 31547701 = 31547774
103 + 31547671 = 31547774
157 + 31547617 = 31547774
457 + 31547317 = 31547774
487 + 31547287 = 31547774
571 + 31547203 = 31547774

Showing the first eight; more decompositions exist.
