Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482402, here are decompositions:

13 + 31482389 = 31482402
53 + 31482349 = 31482402
59 + 31482343 = 31482402
109 + 31482293 = 31482402
131 + 31482271 = 31482402
173 + 31482229 = 31482402
223 + 31482179 = 31482402
229 + 31482173 = 31482402

Showing the first eight; more decompositions exist.
