Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995420, here are decompositions:

43 + 995377 = 995420
73 + 995347 = 995420
79 + 995341 = 995420
193 + 995227 = 995420
367 + 995053 = 995420
397 + 995023 = 995420
457 + 994963 = 995420
487 + 994933 = 995420

Showing the first eight; more decompositions exist.
