Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454062, here are decompositions:

71 + 31453991 = 31454062
131 + 31453931 = 31454062
179 + 31453883 = 31454062
239 + 31453823 = 31454062
383 + 31453679 = 31454062
491 + 31453571 = 31454062
599 + 31453463 = 31454062
641 + 31453421 = 31454062

Showing the first eight; more decompositions exist.
