Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738722, here are decompositions:

11 + 8738711 = 8738722
131 + 8738591 = 8738722
359 + 8738363 = 8738722
383 + 8738339 = 8738722
389 + 8738333 = 8738722
449 + 8738273 = 8738722
491 + 8738231 = 8738722
521 + 8738201 = 8738722

Showing the first eight; more decompositions exist.
