Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139250, here are decompositions:

73 + 139177 = 139250
127 + 139123 = 139250
229 + 139021 = 139250
283 + 138967 = 139250
313 + 138937 = 139250
367 + 138883 = 139250
409 + 138841 = 139250
421 + 138829 = 139250

Showing the first eight; more decompositions exist.
