Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534402, here are decompositions:

59 + 31534343 = 31534402
101 + 31534301 = 31534402
131 + 31534271 = 31534402
233 + 31534169 = 31534402
281 + 31534121 = 31534402
443 + 31533959 = 31534402
479 + 31533923 = 31534402
491 + 31533911 = 31534402

Showing the first eight; more decompositions exist.
