Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574834, here are decompositions:

13 + 31574821 = 31574834
61 + 31574773 = 31574834
157 + 31574677 = 31574834
163 + 31574671 = 31574834
271 + 31574563 = 31574834
337 + 31574497 = 31574834
367 + 31574467 = 31574834
397 + 31574437 = 31574834

Showing the first eight; more decompositions exist.
