Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553126, here are decompositions:

37 + 31553089 = 31553126
109 + 31553017 = 31553126
127 + 31552999 = 31553126
379 + 31552747 = 31553126
433 + 31552693 = 31553126
487 + 31552639 = 31553126
523 + 31552603 = 31553126
547 + 31552579 = 31553126

Showing the first eight; more decompositions exist.
