Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472888, here are decompositions:

37 + 31472851 = 31472888
61 + 31472827 = 31472888
277 + 31472611 = 31472888
409 + 31472479 = 31472888
439 + 31472449 = 31472888
709 + 31472179 = 31472888
739 + 31472149 = 31472888
757 + 31472131 = 31472888

Showing the first eight; more decompositions exist.
