Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553036, here are decompositions:

19 + 31553017 = 31553036
37 + 31552999 = 31553036
157 + 31552879 = 31553036
397 + 31552639 = 31553036
433 + 31552603 = 31553036
457 + 31552579 = 31553036
499 + 31552537 = 31553036
547 + 31552489 = 31553036

Showing the first eight; more decompositions exist.
