Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552784, here are decompositions:

37 + 31552747 = 31552784
103 + 31552681 = 31552784
163 + 31552621 = 31552784
181 + 31552603 = 31552784
397 + 31552387 = 31552784
433 + 31552351 = 31552784
547 + 31552237 = 31552784
577 + 31552207 = 31552784

Showing the first eight; more decompositions exist.
