Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553012, here are decompositions:

13 + 31552999 = 31553012
181 + 31552831 = 31553012
331 + 31552681 = 31553012
373 + 31552639 = 31553012
409 + 31552603 = 31553012
433 + 31552579 = 31553012
523 + 31552489 = 31553012
619 + 31552393 = 31553012

Showing the first eight; more decompositions exist.
