Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480010, here are decompositions:

61 + 31479949 = 31480010
181 + 31479829 = 31480010
193 + 31479817 = 31480010
241 + 31479769 = 31480010
271 + 31479739 = 31480010
313 + 31479697 = 31480010
421 + 31479589 = 31480010
433 + 31479577 = 31480010

Showing the first eight; more decompositions exist.
