Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600274, here are decompositions:

73 + 31600201 = 31600274
157 + 31600117 = 31600274
373 + 31599901 = 31600274
397 + 31599877 = 31600274
463 + 31599811 = 31600274
547 + 31599727 = 31600274
571 + 31599703 = 31600274
787 + 31599487 = 31600274

Showing the first eight; more decompositions exist.
