Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472792, here are decompositions:

19 + 31472773 = 31472792
181 + 31472611 = 31472792
313 + 31472479 = 31472792
433 + 31472359 = 31472792
499 + 31472293 = 31472792
601 + 31472191 = 31472792
613 + 31472179 = 31472792
643 + 31472149 = 31472792

Showing the first eight; more decompositions exist.
