Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473784, here are decompositions:

3 + 31473781 = 31473784
5 + 31473779 = 31473784
191 + 31473593 = 31473784
347 + 31473437 = 31473784
521 + 31473263 = 31473784
593 + 31473191 = 31473784
677 + 31473107 = 31473784
701 + 31473083 = 31473784

Showing the first eight; more decompositions exist.
