Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731402, here are decompositions:

59 + 8731343 = 8731402
89 + 8731313 = 8731402
101 + 8731301 = 8731402
191 + 8731211 = 8731402
263 + 8731139 = 8731402
293 + 8731109 = 8731402
419 + 8730983 = 8731402
509 + 8730893 = 8731402

Showing the first eight; more decompositions exist.
