Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482830, here are decompositions:

7 + 31482823 = 31482830
31 + 31482799 = 31482830
163 + 31482667 = 31482830
199 + 31482631 = 31482830
271 + 31482559 = 31482830
331 + 31482499 = 31482830
487 + 31482343 = 31482830
523 + 31482307 = 31482830

Showing the first eight; more decompositions exist.
