Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731418, here are decompositions:

37 + 8731381 = 8731418
79 + 8731339 = 8731418
97 + 8731321 = 8731418
109 + 8731309 = 8731418
277 + 8731141 = 8731418
307 + 8731111 = 8731418
349 + 8731069 = 8731418
379 + 8731039 = 8731418

Showing the first eight; more decompositions exist.
