Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472796, here are decompositions:

23 + 31472773 = 31472796
73 + 31472723 = 31472796
97 + 31472699 = 31472796
127 + 31472669 = 31472796
163 + 31472633 = 31472796
307 + 31472489 = 31472796
317 + 31472479 = 31472796
347 + 31472449 = 31472796

Showing the first eight; more decompositions exist.
