Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489814, here are decompositions:

61 + 31489753 = 31489814
67 + 31489747 = 31489814
151 + 31489663 = 31489814
163 + 31489651 = 31489814
397 + 31489417 = 31489814
571 + 31489243 = 31489814
751 + 31489063 = 31489814
787 + 31489027 = 31489814

Showing the first eight; more decompositions exist.
