Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706442, here are decompositions:

23 + 8706419 = 8706442
29 + 8706413 = 8706442
191 + 8706251 = 8706442
293 + 8706149 = 8706442
383 + 8706059 = 8706442
431 + 8706011 = 8706442
443 + 8705999 = 8706442
599 + 8705843 = 8706442

Showing the first eight; more decompositions exist.
