Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552994, here are decompositions:

103 + 31552891 = 31552994
163 + 31552831 = 31552994
313 + 31552681 = 31552994
373 + 31552621 = 31552994
457 + 31552537 = 31552994
601 + 31552393 = 31552994
607 + 31552387 = 31552994
643 + 31552351 = 31552994

Showing the first eight; more decompositions exist.
