Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723282, here are decompositions:

79 + 8723203 = 8723282
193 + 8723089 = 8723282
229 + 8723053 = 8723282
241 + 8723041 = 8723282
283 + 8722999 = 8723282
313 + 8722969 = 8723282
571 + 8722711 = 8723282
661 + 8722621 = 8723282

Showing the first eight; more decompositions exist.
