Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535924, here are decompositions:

97 + 31535827 = 31535924
103 + 31535821 = 31535924
127 + 31535797 = 31535924
331 + 31535593 = 31535924
373 + 31535551 = 31535924
421 + 31535503 = 31535924
457 + 31535467 = 31535924
547 + 31535377 = 31535924

Showing the first eight; more decompositions exist.
