Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642434, here are decompositions:

5 + 8642429 = 8642434
131 + 8642303 = 8642434
197 + 8642237 = 8642434
293 + 8642141 = 8642434
401 + 8642033 = 8642434
431 + 8642003 = 8642434
443 + 8641991 = 8642434
617 + 8641817 = 8642434

Showing the first eight; more decompositions exist.
