Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498064, here are decompositions:

61 + 31498003 = 31498064
67 + 31497997 = 31498064
181 + 31497883 = 31498064
193 + 31497871 = 31498064
307 + 31497757 = 31498064
313 + 31497751 = 31498064
337 + 31497727 = 31498064
397 + 31497667 = 31498064

Showing the first eight; more decompositions exist.
