Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480542, here are decompositions:

13 + 31480529 = 31480542
101 + 31480441 = 31480542
109 + 31480433 = 31480542
151 + 31480391 = 31480542
173 + 31480369 = 31480542
193 + 31480349 = 31480542
283 + 31480259 = 31480542
439 + 31480103 = 31480542

Showing the first eight; more decompositions exist.
