Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472594, here are decompositions:

3 + 31472591 = 31472594
7 + 31472587 = 31472594
157 + 31472437 = 31472594
463 + 31472131 = 31472594
487 + 31472107 = 31472594
541 + 31472053 = 31472594
661 + 31471933 = 31472594
883 + 31471711 = 31472594

Showing the first eight; more decompositions exist.
