Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498532, here are decompositions:

3 + 31498529 = 31498532
19 + 31498513 = 31498532
61 + 31498471 = 31498532
409 + 31498123 = 31498532
421 + 31498111 = 31498532
463 + 31498069 = 31498532
523 + 31498009 = 31498532
601 + 31497931 = 31498532

Showing the first eight; more decompositions exist.
