Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730430, here are decompositions:

53 + 8730377 = 8730430
89 + 8730341 = 8730430
167 + 8730263 = 8730430
173 + 8730257 = 8730430
281 + 8730149 = 8730430
347 + 8730083 = 8730430
353 + 8730077 = 8730430
431 + 8729999 = 8730430

Showing the first eight; more decompositions exist.
