Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460698, here are decompositions:

41 + 31460657 = 31460698
89 + 31460609 = 31460698
149 + 31460549 = 31460698
257 + 31460441 = 31460698
359 + 31460339 = 31460698
419 + 31460279 = 31460698
431 + 31460267 = 31460698
569 + 31460129 = 31460698

Showing the first eight; more decompositions exist.
