Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553282, here are decompositions:

3 + 31553279 = 31553282
193 + 31553089 = 31553282
283 + 31552999 = 31553282
601 + 31552681 = 31553282
643 + 31552639 = 31553282
661 + 31552621 = 31553282
853 + 31552429 = 31553282
1213 + 31552069 = 31553282

Showing the first eight; more decompositions exist.
