Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501292, here are decompositions:

61 + 31501231 = 31501292
73 + 31501219 = 31501292
211 + 31501081 = 31501292
283 + 31501009 = 31501292
313 + 31500979 = 31501292
373 + 31500919 = 31501292
421 + 31500871 = 31501292
439 + 31500853 = 31501292

Showing the first eight; more decompositions exist.
