Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758742, here are decompositions:

73 + 8758669 = 8758742
193 + 8758549 = 8758742
229 + 8758513 = 8758742
241 + 8758501 = 8758742
283 + 8758459 = 8758742
313 + 8758429 = 8758742
409 + 8758333 = 8758742
463 + 8758279 = 8758742

Showing the first eight; more decompositions exist.
