Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749418, here are decompositions:

61 + 8749357 = 8749418
109 + 8749309 = 8749418
199 + 8749219 = 8749418
211 + 8749207 = 8749418
277 + 8749141 = 8749418
331 + 8749087 = 8749418
439 + 8748979 = 8749418
541 + 8748877 = 8749418

Showing the first eight; more decompositions exist.
