Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535048, here are decompositions:

37 + 31535011 = 31535048
67 + 31534981 = 31535048
229 + 31534819 = 31535048
379 + 31534669 = 31535048
397 + 31534651 = 31535048
487 + 31534561 = 31535048
547 + 31534501 = 31535048
607 + 31534441 = 31535048

Showing the first eight; more decompositions exist.
