Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730742, here are decompositions:

5 + 8730737 = 8730742
113 + 8730629 = 8730742
131 + 8730611 = 8730742
269 + 8730473 = 8730742
389 + 8730353 = 8730742
401 + 8730341 = 8730742
431 + 8730311 = 8730742
479 + 8730263 = 8730742

Showing the first eight; more decompositions exist.
