Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480894, here are decompositions:

101 + 31480793 = 31480894
131 + 31480763 = 31480894
461 + 31480433 = 31480894
503 + 31480391 = 31480894
521 + 31480373 = 31480894
947 + 31479947 = 31480894
1013 + 31479881 = 31480894
1091 + 31479803 = 31480894

Showing the first eight; more decompositions exist.
