Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472862, here are decompositions:

11 + 31472851 = 31472862
13 + 31472849 = 31472862
23 + 31472839 = 31472862
89 + 31472773 = 31472862
139 + 31472723 = 31472862
163 + 31472699 = 31472862
193 + 31472669 = 31472862
199 + 31472663 = 31472862

Showing the first eight; more decompositions exist.
