Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473010, here are decompositions:

47 + 31472963 = 31473010
83 + 31472927 = 31473010
131 + 31472879 = 31473010
197 + 31472813 = 31473010
311 + 31472699 = 31473010
347 + 31472663 = 31473010
419 + 31472591 = 31473010
509 + 31472501 = 31473010

Showing the first eight; more decompositions exist.
