Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731772, here are decompositions:

61 + 8731711 = 8731772
73 + 8731699 = 8731772
163 + 8731609 = 8731772
193 + 8731579 = 8731772
241 + 8731531 = 8731772
271 + 8731501 = 8731772
409 + 8731363 = 8731772
433 + 8731339 = 8731772

Showing the first eight; more decompositions exist.
