Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731396, here are decompositions:

53 + 8731343 = 8731396
83 + 8731313 = 8731396
257 + 8731139 = 8731396
293 + 8731103 = 8731396
419 + 8730977 = 8731396
449 + 8730947 = 8731396
467 + 8730929 = 8731396
503 + 8730893 = 8731396

Showing the first eight; more decompositions exist.
