Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999430, here are decompositions:

41 + 999389 = 999430
53 + 999377 = 999430
59 + 999371 = 999430
71 + 999359 = 999430
101 + 999329 = 999430
191 + 999239 = 999430
197 + 999233 = 999430
281 + 999149 = 999430

Showing the first eight; more decompositions exist.
