Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552454, here are decompositions:

61 + 31552393 = 31552454
67 + 31552387 = 31552454
103 + 31552351 = 31552454
151 + 31552303 = 31552454
397 + 31552057 = 31552454
421 + 31552033 = 31552454
457 + 31551997 = 31552454
601 + 31551853 = 31552454

Showing the first eight; more decompositions exist.
