Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553292, here are decompositions:

13 + 31553279 = 31553292
19 + 31553273 = 31553292
31 + 31553261 = 31553292
59 + 31553233 = 31553292
73 + 31553219 = 31553292
79 + 31553213 = 31553292
109 + 31553183 = 31553292
131 + 31553161 = 31553292

Showing the first eight; more decompositions exist.
