Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480370, here are decompositions:

3 + 31480367 = 31480370
241 + 31480129 = 31480370
349 + 31480021 = 31480370
409 + 31479961 = 31480370
421 + 31479949 = 31480370
541 + 31479829 = 31480370
577 + 31479793 = 31480370
601 + 31479769 = 31480370

Showing the first eight; more decompositions exist.
