Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472698, here are decompositions:

29 + 31472669 = 31472698
107 + 31472591 = 31472698
197 + 31472501 = 31472698
347 + 31472351 = 31472698
359 + 31472339 = 31472698
797 + 31471901 = 31472698
911 + 31471787 = 31472698
1031 + 31471667 = 31472698

Showing the first eight; more decompositions exist.
