Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552772, here are decompositions:

79 + 31552693 = 31552772
151 + 31552621 = 31552772
193 + 31552579 = 31552772
283 + 31552489 = 31552772
379 + 31552393 = 31552772
421 + 31552351 = 31552772
463 + 31552309 = 31552772
739 + 31552033 = 31552772

Showing the first eight; more decompositions exist.
