Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981434, here are decompositions:

37 + 981397 = 981434
43 + 981391 = 981434
61 + 981373 = 981434
151 + 981283 = 981434
163 + 981271 = 981434
193 + 981241 = 981434
283 + 981151 = 981434
367 + 981067 = 981434

Showing the first eight; more decompositions exist.
