Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641742, here are decompositions:

73 + 8641669 = 8641742
139 + 8641603 = 8641742
199 + 8641543 = 8641742
223 + 8641519 = 8641742
229 + 8641513 = 8641742
271 + 8641471 = 8641742
313 + 8641429 = 8641742
433 + 8641309 = 8641742

Showing the first eight; more decompositions exist.
