Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537292, here are decompositions:

19 + 31537273 = 31537292
139 + 31537153 = 31537292
349 + 31536943 = 31537292
421 + 31536871 = 31537292
463 + 31536829 = 31537292
499 + 31536793 = 31537292
811 + 31536481 = 31537292
1069 + 31536223 = 31537292

Showing the first eight; more decompositions exist.
