Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453562, here are decompositions:

61 + 31453501 = 31453562
79 + 31453483 = 31453562
229 + 31453333 = 31453562
241 + 31453321 = 31453562
313 + 31453249 = 31453562
421 + 31453141 = 31453562
523 + 31453039 = 31453562
541 + 31453021 = 31453562

Showing the first eight; more decompositions exist.
