Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747774, here are decompositions:

31 + 8747743 = 8747774
37 + 8747737 = 8747774
73 + 8747701 = 8747774
97 + 8747677 = 8747774
151 + 8747623 = 8747774
157 + 8747617 = 8747774
367 + 8747407 = 8747774
523 + 8747251 = 8747774

Showing the first eight; more decompositions exist.
