Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455334, here are decompositions:

41 + 31455293 = 31455334
137 + 31455197 = 31455334
173 + 31455161 = 31455334
263 + 31455071 = 31455334
293 + 31455041 = 31455334
431 + 31454903 = 31455334
461 + 31454873 = 31455334
467 + 31454867 = 31455334

Showing the first eight; more decompositions exist.
