Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489734, here are decompositions:

11 + 31489723 = 31489734
13 + 31489721 = 31489734
61 + 31489673 = 31489734
71 + 31489663 = 31489734
83 + 31489651 = 31489734
163 + 31489571 = 31489734
193 + 31489541 = 31489734
271 + 31489463 = 31489734

Showing the first eight; more decompositions exist.
