Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453104, here are decompositions:

83 + 31453021 = 31453104
127 + 31452977 = 31453104
131 + 31452973 = 31453104
311 + 31452793 = 31453104
373 + 31452731 = 31453104
383 + 31452721 = 31453104
421 + 31452683 = 31453104
521 + 31452583 = 31453104

Showing the first eight; more decompositions exist.
