Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537954, here are decompositions:

83 + 31537871 = 31537954
131 + 31537823 = 31537954
233 + 31537721 = 31537954
263 + 31537691 = 31537954
521 + 31537433 = 31537954
563 + 31537391 = 31537954
641 + 31537313 = 31537954
647 + 31537307 = 31537954

Showing the first eight; more decompositions exist.
