Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445734, here are decompositions:

11 + 31445723 = 31445734
41 + 31445693 = 31445734
53 + 31445681 = 31445734
71 + 31445663 = 31445734
83 + 31445651 = 31445734
113 + 31445621 = 31445734
191 + 31445543 = 31445734
227 + 31445507 = 31445734

Showing the first eight; more decompositions exist.
