Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553162, here are decompositions:

73 + 31553089 = 31553162
163 + 31552999 = 31553162
271 + 31552891 = 31553162
283 + 31552879 = 31553162
331 + 31552831 = 31553162
523 + 31552639 = 31553162
541 + 31552621 = 31553162
673 + 31552489 = 31553162

Showing the first eight; more decompositions exist.
